I'm a gaming community leader. We are looking at setting up a nice forum for our members. Xenforo is one I'm looking at, as a potential candidate for use. It looks nice and simple to use, but this leads me to my question: What is the advantage to paying the licensing fee on Xenforo instead of just using something free, like phpBB or SMF?
It seems like Addon/Mod support is there for both, and forum management systems aren't all that different. In other words, what am I getting for the nearly $150 I'd be spending on Xenforo? Is it worth it for a small community?
