No problem. So the same way you typed this message you can do on XGC Counter Strike, my Section Leader forum's page etc. simply go to Counter Strike's forum page, and click on one of the games (anything that doesn't say 'Sticky' next to it is fair game), click on a thread you want to post on and type a message in the quick reply box & hit post quick reply.
Remember, keep it PG 13 though
if you need any more help hmu
