Newest server?

[Umo]

September, not December. All the servers have been up since a couple weeks after release.

My fault, I thought they created a few new Worlds in order to alleviate congestions so I checked creation date of aforementioned World's dedicated forums, giving as result December instead of September.
Hmm... However, I don't understand this:

Each of those forums also has a "Welcome to..." sticky, dated when the forum was created. For the later servers, that's maybe a day off from when the server itself was added.

That contradicts your next post, right?

Anyways, Iymala hit the nail on this, so the matter stands resolved.
