It'd actually be nice to have the Articles/FAQ/Links pages return in some fashion, though they aren't used by every group out there. Beyond that, having titles return is a big one or something similar since most group admins, myself included, use them to form an investment system where more trusted/veteran members fall into upper classes. Personally, I'd love to see the inclusion of a badge system where you can adorn a member of your group with small symbols to show their dedication or actions in group. (ex: been to 5 gamenights? Get one!) Obviously the conditions for these would be set by leaders, but it'd be pretty cool.
