Moving Day currently delayed...
As mentioned in the Site Problems thread, we're looking at moving to a better hosting situation. In spite of the white screen issues, KnownHost has been excellent (the current problems are almost certainly the fault of some inefficient scripts in the phpbb2 code coupled with our current size), but this will give us more resources and hopefully more control over such problems.
jeep and Flay are still working on migration to phpbb3 - this won't affect that in any way, we'll just likely be on a new server first.
We are tentatively scheduling the move for the weekend of October 17th/18th. In theory, we should be able to copy over everything but the databases before then, and only disable the forums when we are actually moving the databases (so that no new posts are added while we move, and so the white screen doesn't pop up while we're moving and screw things up). It may take a while to move them (it's a lot of data), and something might come up to slow us down, but hopefully it won't take long - our move in January only took 2 days, and I was doing that without any help.
If you are modding a game which will be running that weekend, you might consider working your deadlines around the downtime to minimize the effect on your game.
While the forums will be disabled during the move, I will likely be opening the Shelter forum, both for discussion while we're down and also, possibly, for a Marathon Day to bridge the downtime with lots of Mafia. More details on that to come, but start planning for that. We'll make sure to put links in big, obvious places both to the Shelter/Marathon Day forum and to the new server once it is ready for action.
