Half-Life - Opposing Force competition

me and some friends were thinking of organizing a half-life - opposing force competition. we were thinking of gathering at least 32 people [if the number is exceted we go for 64 and so on, the more the marryer ]. the ruls would be:
- at the beggining the players will be paired at random
- the matches will be played 1 on 1 with one or more observers to ensure fairness
- the contest will be played in two classaments ... the first one will be composed of the all the winners of the inital matches and the seccond of the ones that have lost
- you will have to loose twice to be eliminated
- the games will be played at an hour that the two players will agree upon, for each game there will be given three days in wich the players should contact eachother and agree upon the time of the game
- there will be three 15 minute games, two on crossfire and one on a neutral map
i guess that is about it ... to sign up go to http://www.computergames.ro/forum/showthre...ad.php?t=217364 and post youre nick, country/region and a yahoo messenger or an msn id. unfortunatly the first few posts on that forum are in romanian , we didn't think of going international but everyone will be asked to speak in english from now on. cheers
