I have just purchased Xenforo and its offline now as I am presently building in the topic boards. I am in need of an anti spam add on and from what I have read and researched so far this one seems to be the best. I don't have sufficient privilege to post on the add on section that is why I am asking here so please bear with me. I wont mind paying for it too if it is for sale. Thanks in advance for your replies.
