Noobstown is not 1.5.2 yet, so don't update  ;)

It's only a Snapshot, you can't update to the main version release yet without having to switch your jar out.

its 1.5.2 now

OMG I haven't been home to update YES hourses

Yeah but what I mean about "it is only a snapshot" means if you update, you should still be able to play on the server, at least as far as I know, if it was 1.6 official release it would be different, cause it is new blocks and all that stuff that you wouldn't have on a older version.

But if it is just bug fixes and other minimal changes, it should still work, at least it has in the pass.
