The closer the day vB3 gets released, the more worried I get... basically because my site is so hacked that it would be a nightmare to upgrade and lose all the changes.
I'm not only talking about cosmetic changes. My whole admin control is modified for different levels of admins. Plus my multiple levels of suspension and banning - all hardcoded, and all potentially worthless in vB3... the headaches I get thinking and worrying about it...
