In an attempt to sort out the msmvps.com site, I spent last night cleaning out the databases (over 9gb of pure shite). Community Server really should have an option (an easy one to find) that either purges or stops the logging at certain limits.
Anyway, Susan also upgraded us to Community Server 2007 last night. Because of that some of the skins on the blogs will look different, over the next few days we will get it sorted.
