Can steam do that? And it's not like it's a seperate program. Just a gui so that when your friends are on you can join right to the server they are on. Plus none of my friend's computers can run any steam games (Just wow :/) and currently until I update mine neither can I.
Actually, this is a good idea. And yes, you can join your friends on STEAM, but Blockland isn't on steam, and not many people who have STEAM(or most likely GMod 10) play Blockland. 'Cept me. :)
Not sure why I said game. >.>
