Dennis,
The mechanism exits. 5.2.2 ships with a comunity of practice (COP) module, which offers more advanced solutions, effectively upgrading the subsite concept. I feel Dot folio should be offered in the same fashion. Maybe we should create a second layer.
Subsite enhancements/display options
1. default.
2. COP.
3. Dotfolio
4......????
Cheers
Ben
