I really like where xenforo is going and even in this beta stage the features are enough to make me happy. I have a existing review website in a particular niche built on php.
My first question is when a user submits a review of a product i would like to update their activity feed. Would this be possible? Will this cause any issues since it would be a external xenforo activity.
My second question in order to build the best / flexible user integration system am i better off building it on top of xenforo or building my own user registration system and linking the accounts? via a extension or something along of those lines
