If you encounter any problems or other "funkiness" as you start using the new forums, please post in the Bug Fix forum. It will help us keep track of any outstanding issues.
Also, please note that the old threads will be coming. There are dozens of gigabytes of files that need to be grepped, splitup into segments, databases re-initialized, after which the data has to be translated to the new system to re-read in. It's a Herculean task and we're on it. Please be patient.
