Using VAC Chaos to create lobbies is completely choob. There is another way though. It's called modloader. It uses the .gsc files that you can create (using a type of c++ language) to create modded lobbies. Now, this website isn't very big into modding lobbies in my opinion, but there are some useful tools here. Search for Modloader on this site, google ffViewer, and learn how it works. It will seem extremely complicated at first, but becomes extremely fun later on. Hope this helps
