That sounds like an interesting idea, but the problem with that might be finding a time where we are all online together and can get together. Sometimes I'm offline, sometimes I'm online, others may be on 24/7, some may be offline on most days. A little office sounds cool, but that might be the problem if you want us all to get together at the same time.

I just had an idea for a map. How about a tall, mountain-ish area with some rocks, and a few plants/trees, with a river going through it, and maybe it could be night all the time (If not possible, most of the time)? Something like this:
-Heightmap for that created really quickly, it probably isn't very good-
It could be hidden somewhere in a high part of Oasis maybe.
