Found on the iRacing forums recently. Thanks to David Correia for putting this together and for allowing me to share it with everyone. There is a download-able version at the bottom of the page.

Administrative Chat Commands
- Some commands may be shortened, the bolded part of the commands are the shortest form acceptable.
- <> means a required parameter.
- [] means an optional parameter.
- is the name or number of a driver, same as described above.
- [message] is an optional message to be appended to any admin command.
eg: the command ‘!remove #32 Banning for reckless driving.’ would send out the notification:
‘#32 was removed from the system. Banning for reckless driving.’ to all drivers.

Command	Action
!help or !?	Print list of commands available, or list additional information about individual commands.
!admin [message]	Give other drivers admin privileges
!nadmin [message]	Remove admin privileges from driver.
!remove [message]	Permanently remove a driver from the race, can remove spectators as well
!yellow [message]	Throw a yellow if not already active, issue during 1 to go, to extend the caution
!waveby [message]	Move car up to next lap and send to the end of the pace line
!advance [message]	Advance to next session (qualify to grid, etc).
!chat [driver]	Enable chat for all drivers, If driver is specified, re-enable chat for that driver.
!nchat [driver]	Disable voice/text chat for all drivers except administrators, If driver is specified, disable chat for that specific driver only
!spchat [message]	Allow spectators to chat with drivers.
!nspchat [message]	Disable spectator to driver chat.
!black [time] or [L(laps)]	Give a driver the black flag, Default is a stop and go, optionally specify time or laps to hold.
!dq  [message]	Disqualify a driver from the race, but do not remove them from the server.
!eol  [message]	Move driver backwards to end of pace line.
!clear [message]	Clear all pending or active black flags, dq’s or eol’s for a driver.
General
/#	Send driver priviate message
r	From either the driving screen or the session screen responds to the last person who private messaged you.
/rc	Sends a message to the admins of current event. (/rc is short for race control)
/all (admin only)	Sends a chat message to all drivers even if chat is disabled.
Here is the download-able spreadsheet version	Admin Control List Version 1.00 Last Updated 2010-08-03 List of Admin controls for iRacing Hosted sessions.

Yeah, you could say I’m looking forward to this one.

Excellent kick start by Doug Gegenheimer, a fellow Mid-South club member.

I thought I’d give it a go to record some of my replays and upload them to Youtube, but didn’t know where to start. I found this on the forum and think it will get me up and running pretty fast.

I capture in FRAPs 1280×720 (full res), 30FPS (this requires you to change the ingame display resolution to 1280×720). To eliminate the choppiness, make sure your replay never drops below 30fps.

I edit the clips in Premiere, and export out uncompressed avi.

I then use VirtualDub to convert and resize the final file.

Things you’ll need:
Virtual Dub: http://virtualdub.sourceforge.net/
Xvid Codec: http://www.xvid.org/Downloads.43.0.html
Lame MP3 Codec: http://www.free-codecs.com/download/Lame_Encoder.htm
VLC Media player (optional): http://www.videolan.org/vlc/

Install all 3.

To convert your video, open VirtualDub. Once open,

- Select File/ Open Video File, to open the file you want to convert
- Select Video/ Compression to open the list of video codecs you can use to compress the video
- In the list on the left, select Xvid MPEG-4 Codec, then click the Configure button
- For Xvid Configuration settings, I use:
Profile @ Level: (unrestricted)
Encoding type: Single Pass
Target Bitrate (kbps): 6000 (5000 min for Youtube “Watch in HD” button)
Everything else I leave alone
- Click Ok twice to return to main VirtualDub window

- Select Audio/ Full Processing mode

- Select Audio/ Compression
- In the list on the left, select Lame MP3,
- on the right, select 48000Hz, 160kbps CBR, Stereo 20KB/s
- Click Ok

-Click File/ Save as AVI to export the video.

If you are using 5.1 or other surround sound modes, you might get an error when encoding starts. I resorted to running the game in Stereo mode so that the fraps capture is Stereo and not surround.

Depending on your system, Windows Media Player can start to choke on the 720p file. I recommend VLC instead, it plays the videos much smoother.

Also, you don’t need to worry about the editing and saving as uncompressed avi in Premiere. Just FRAPs, and convert in VD. You can also use VD to join multiple captures.

G’day Folks,

Dave Kaemmer has written up and excellent explanation of what is coming in tire modeling from iRacing. I’ll warn you now, it’s full of physics and mathematics, however if you want to understand just how difficult it is to get right, you should have a read HERE

If you are new to physics and would like an overview of how it works in relation to racing simulations, I’d suggest reading up on “The Physics of Racing” first. There is a copy here

I’ve been enamoured with physics and how it relates to cars for a very long time and even started writing my own game at one point. The interesting thing is that there is so much that is known, suspension geometry, shock physics, that is straight forward to model. (I try not to use easy) A lot of black box physics engines can do most of that stuff to varying degrees.

The tough part is the tire physics, mainly due to the secretive nature of the business. There is also the fact that a game / simulation will take the tires much further over the edge than even the tire companies test and that is a black morass of fuzzy logic and out of the box mathematics. Why? Well mainly due to the existing formulas for calculating forces acting on a tire at the edge explode in corner cases when they get over the edge making the math get all sorts of crazy.

Have a read of the excellent articles and post your questions. I’m thinking I might dive back into it a little to at least be able to answer questions. There are some open source basic looking physics engines around that I also might have a re-look at to show how it works in code … if anyone is interested of course.

Kind Regards,

Shane

Saw a link to this on the iRacing.com forum today and it’s well worth sharing.

While the commentary has been added from Nascar on Fox. The video is all iRacing from some of the best in the business.

The World Championship races are being broadcast online with commentary and you can get details from www.iRacing.com
