I feel that this very important issue needs to be resolved once and for all: The logo quite clearly says "xenForo", and yet I see so many writing it "XenForo". And what about the abbreviation? If "xenForo" is correct, then the abbreviation should surely be "xF"? What is the meaning of "xenForo" anyway? I can imagine the "Foro" part having to do with forums. I'm not sure about "xen" though. Does it have to do with the Zend framwork?
