id Software's Todd Hollenshead updated his .plan with info for those that want to help test out their new beta Quake III: Team Arena server, which offers a fix for the "guard" exploit that was recently discovered. Here's the info, and if you're interested in joining, you can get the IP addresses in his full update:

We're testing a new beta server-side executable that stops the "Guard" exploit. If you want to help us try it out, come and join on one of the following:

We'll probably jump on the Terrain server here in a little bit to maybe play a little id vs. everyone CTF and monitor the stability of the executable. You don't have to download anything new since it's server only. Just join and play.

If you have any feedback specific to the server patch, please email it to bugs@idsoftware.com and put "New Executable Feedback" in the subject line. Please DO NOT email id employees directly as your feedback will just get lost.
