We're aware of problems in the registration/avatar and online/offline indicator department, not to mention some erratic post-counting and yes, the fact the 'Joined' date has reverted to US MMDDYYY format.
However, our digital team is currently reorganising and various people have been on holiday/are no longer with us, so we've been a bit shorthanded of late. We hope to look into some of the bigger hitches on the site soon, and then we'll eventually get on to the smaller, but definitely niggling, stuff.
