So I just went on the RDN and read what I think are some of your posts (Citrus Rain?). The group and the page on Facebook are two separate entities and they have been since you left.
The page in a nutshell: It has one admin, the admin is the only person who can post as the page or onto the page, and he posts occasionally about meet ups he creates for his CMU friends. I personally have no idea who the admin there is. We (the group) don't have communication with those people.
The group in a nutshell: We spam random pony media day in and day out. 4 admins (the leader of which is me), it was 5 until one of them left a few days ago. The admins don't do much there except add new members, moderate anything that has potential to be offensive, and occasionally create medium-tiny meetups. We didn't even know there was a G+ group until someone posted on our wall about it today. We would be more than happy to finally rejoin forces with our long lost brothers from G+.
For the page, on the other hand, this is doubtful.
Also~, could I pretty please have admin on the Steam group? We tried to get some TF2 going at one point, and I think it would have been more effective if I could have created an event for the group.
