Hey @DexLuther - I hadn't seen this idea, I have not (yet) read all the suggestions made before I joined the team.
The central idea of having one space station to which all players are auto-invited (including new players joining the server, and without the admins needing to type any commands) is a good one. That should be easy enough to implement, though it means adding yet another config.
Having players spawn in that dimension instead of on the Overworld is something server owners will have to figure out. I'm fairly sure Bukkit plugins for example Essentials can do this, but I don't remember exactly how. Alternatively, there's a mod named
Perfect Spawn. Either way, it is not necessary for GC to do this.
Server owners will need to think carefully about whether they really want to do this, given that space station dimensions have no gravity now (in GC3) so noobs will find it challenging to move around and might leave the server. There's also an issue that Essentials teleporting is - apparently - unable to teleport players to a sealed space, because it thinks the GC breathable air blocks are solid, so it will put teleporting players outside the space. Which isn't good, as that should be hard vacuum.
A better idea might be a dimension which "looks" like a spacestation but is actually Overworld-type with regular air and gravity. That's something server owners can build for themselves, though I guess they would appreciate borrowing the sky from a GC space station dimension, if there are windows etc - can probably even make that spin.
For the historical MCPC+ comments earlier in this thread, I hope server admins have by now all read this:
