Hi all !
I encourage you all, and specifically you themers guys and girls, to have an urgent deep look into infinity "anti framework" (discovered on a reviw on wpmu.org)
This just... kills !
Theming possibilities are quite infinite, you can build your own 'theme options', cascadind thmes childs...
Even me, not a dev, is impressed.
Guys here, i sincerly encourage you tu build themes on this and create some "woaw effect" themes. Specially for buddypress, of course natively supported by infinity. For other, few dev is required to build somtehing really "woaw", and the must : it is very very low ressources eater !
