If you updated your All-Seeing Eye yesterday, you would have noticed that QUAKE4 support has been added, well almost fully added. While the QUAKE4 filter has been added to the All-Seeing Eye server browser, the scanners which provides you a list of server isn't working yet. So if you really want to use The All-Seeing Eye server browser, you can grab this server list and import it into the program.
One other note... Many of you have probably noticed that the in-game server browser only lists up to 1000 game servers. From what I can tell, that isn't a problem with the in-game server browser itself, but a problem with the QUAKE4 master server run by id Software in Texas. PQ4 will try to contact id for a statement about this problem.
