I also agree, To add Xenforo also boasts a great community with first class mods and a development team that I could only explain as military focused but at the same time helpful and active within the forums.
I've found it to be nothing short of spectacular! I've only been using XenForo for a couple of months but my experience so far has been an absolute pleasure.
The community here has been a tremendous help and the team members are masters of their craft.
Its safe to say, I'm addicted to XenForo
Indeed, Xenforo is the best! And I love the fact that there is no dedicated place for 'testimonials', it's much better this way in a thread where even other people can share their own opinion adding more to what the OP posted
