How do CoD clans organize themselves? I used to play Ghost Recon in clans and they used Gamespy Arcade which shows a list of servers and you just made a room like: "(your clan name) vs.???". But there's so many CoD servers and players how do you organize yourselves for clan matches.
Typically, Clans have their own server to begin with. Other clans look for servers advertising a clan, and jump on to challenge'em to an informal scrim. For league and ladder play, websites such as www.teamwarfare.org http://www.worldogl.com/ and http://www.caleague.com/ operate a match system that makes it easy for clans to challenge each other and keep track of scores and rankings.
Mirc and Xfire are the number 1 communicating programs.
most clans use ventrillo or clan speak, or just a instant message program like xfire. Most clans have their own web sites and servers
