I definitely agree with this. When XF first came out, I joined up on a site and wanted to post so much more.Your forum isn't automatically going to do better because you go with a paid software. However, there will be other benefits. I do think that paid software tends to look much better and feels much better for the end-user as well. That usually means they are happier to post a lot on your forum which in the end is great for you and the forum.
