As many of you probably know, we have been working on new forum infrastructure for some time now, because the existing forum software is extremely outdated and unstable. Unfortunately, these buggy old forums have finally caused bigger problems for the rest of the site, and with that in mind, we've been forced to implement the new forum software we've been working on a bit earlier than we initially anticipated. Beginning today, the current RT forums will be made permanently read-only and migrated over to the new software. Within a week, we should have the new forum software up and running and you will be able to create new threads and participate as you always have with the new software.
We apologize for the extremely short notice and any inconvenience it may cause; rest assured we wouldn't have done this if the existing forums didn't pose an immediate threat to the stability of the site. Thanks for your patience and understanding, and we'll see you back here soon!
