Improve your internal communication by allowing staff to interact and discuss in an online corporate community.
Classic bulletin board experience
Pros: Used Invision Power Board for a few years and it was one of the best solutions in the market. It's highly customisable and it's in fact mobile friendly. Great experience so far.
Cons: I think they could offer a free plan or something cheaper, even they offer a lot of features. Also it's not that easy to create new themes and templates.
