User-created groups already sort of exist now that everyone can create their own boards. But how about bringing back official H.E.R.O./E.V.I.L./P.I.R.A.T.E./N.I.N.J.A. boards? There could be a group button at the top of the page where you can choose one of the four groups to join, then the group's board would appear in the 'official' section of the board list on the right. Comments anyone?
