The forum software on Nightscrawlers will be upgraded either tonight or early tomorrow. As with any upgrade, there will inevitably be problems; we have a comprehensive plan to make sure all hacks are carried over and code doesn't point to anything that doesn't exist anymore, but we all know what happens to the best-laid plans of mice and men.
I will post an update in this thread when the upgrade has completed; at that time, this thread will be open for roughly a month to report any problems that you may have that may be related to the upgrade. This includes problems with the forum's features or any hacks that may be misbehaving/missing.
No data will be lost whatsoever in this upgrade.
