1. For multiplayer compatibility, each version of SoundRTS is a different game. The mod must match exactly too, sooner (until 1.2 alpha 9) or later (since 1.2 alpha 10 where only one server per SoundRTS version is needed).
2. Only the "slj" server is on the metaserver. It runs 1.2-c2 which is fine. There is no server called "coolfortheblind" on the metaserver right now. Note that 2 servers would use the same port unless you use the -p command line option.
Version 1.2-c2 contains crazymod9beta9. For a server it doesn't matter because only one server is needed for all the mods.
People can use any version of the mod on a 1.2-c2 server.
Maybe I should update the included mod to crazymod9beta10 and even include crazymod8.3? or just provide the vanilla SoundRTS without mods?
About curating maps, sound packs and mods, I'm not sure if I could do this. I'm focusing on the code at the moment.
