I used this software years ago, with vbulletin. Its was a complete disaster all the time, endless bugs yielding literally hundreds of hours in lost time.
I want a wiki for my forum but after my experience with this, I am very hesitant to ever use something that leaves content completely screwed up if its disabled. So again, my rating on this is code is to forewarn members of the setbacks should you have the same experiences as I did. Looking ahead, if this wiki has been improved and should you discontinue updating it, thus forcing xenforo users to have to uninstall it... what would the wiki bbcode content look like? Would it have all sorts of special bb code broken?
