This is probably not directly related to the migration, but I was looking for the member list the other day and couldn't locate it (Google can find individual members though). Should I look harder? I thought it was just a tab under 'forum'. Sorry if I'm just being dozy here .
It's disabled at the moment. Apparently with so many members it can cause huge issues for large boards. It might come back, I am just waiting until the vBulletin consultant we've hired gives his input. It's often a common phrase among large forum owners "memberlist strikes again!" for those having major issues.
