First, the email issues:
We've been recently blocked by Hotmail/Live/MSN because many users have reported email from us as spam. If you do not wish to receive email, please go into your profiles, and remove your email address.

From this point on, any email from us reported as spam that is not actual spam will result in a ban.

Now, the rest:
After almost a week of hassle, things appear to be operating at normal capacity again. One of our two dead servers has been fully repaired, and the other is almost done. The tracker, browse, invites, and post editing appear to work as intended. Any outstanding issues as a result of the move and its complications should be posted in the Bug Reports forum
