To engage more in the community's, a way to add gamification to the pages would be great. Something like experience points for posting, and different levels people can earn, unique stickers that people can apply to posts, but only exists within that community. Things to make being a member of the community more fun...
Perhaps even custom user images / badges for members, and rewards within the community... To make engagement and being part of them more fun.
Also, being able to add ads to the pages would be good.
Hmmmmm that would be pretty cool indeed, but at the same time it sounds like a very custom implementation which should be per communities like what leofinance does with their token IMHO. Not a "staple" feature.
Ads definitely ! I think there are some issues that we may need to sort out with front ends.
