Are there IRC channels, hamachi groups, whatever dedicated to Star Control?
I've spent a few minutes googling, and the best I've found so far is #starcontrol on EFNet, which appears to be relatively low activity at first glance.
why don't we just set up a lobby in the UQM melee game that lets you go to a server where people are? You could then challenge people to games through it with some sort of protocol. To simplify it could just be an IRC chatroom for beta versions.
I think I asked about this from someone in the channel, and they told me that it was a hell to make even the IP entering box or something like that. So if you can program, do it yourself, lots of fellows could have use for it.
