I dont know alot about the server side of MTA but http://forum.mtavc.com/viewtopic.php?t=11098 might have something to help out with any other problems which might occur. Also make sure the server patch is installed.
T is to speak in game. Just press T on your keyboard and enter the message and then click enter to send.
Some controllers do work for MTAVC but the autoaim or lockon feature dosnt work. most people find it also easier to play with mouse and keyboard.
Im a VC fan like you also, so are many other people. Some people think the team will go back to VC BLUE after a release of MTASA, However these are just rumors but im sure we will see another VC Version out again one day.
Even if a ref was in the match, what ever happens at the end we will just here more flaming and bitching from both clans heh. Because one clan wont be able to hand with the defeat.
Actually i think his just talking about the lag or high pings which may come from you at times, Just like what XII were talking about in the A* match the other week hehe
