And adding to this. When you come and read all these mods or features each person says XenForo "must, must, must have now". Can you imagine what the software would be like 12 months from now if Kier and Mike added them all, it would fast become a bloated load of junk. Some of us have seen this happen, thankfully Kier made it clear from the start they didn't want to head down that same (mistake of a road) made by another certain forum software.
Of course we all want to see XenForo grow and improve with some features, that's only normal and it does still lack things which may come later. But you have to draw the line somewhere otherwise it would just get turned into bloated rubbish. Worth keeping in mind also, that many of the people who scream black and blue for this and that to be added, 12 months later ain't running a forum anymore.
