GSC doesn't show Arma?

[goodguyswearblack9]

As suggested by a member of these forums, I started using Gametracker to find multiplayer games. I want to launch games using GSC, but when I go in GSC Arma isn't there. Do I have to add addition games to GSC that are on Gametracker? I've got COD4 to work but need to get Arma there too. I'm not totally sure yet how to use GSC, but it would be nice to use on Arma if possible.

I'm sorry if this isn't the right place to ask this, and thanks for your help.

I think you would have to add it to your GSC settings
