Hi! I'm really interested in purchasing xenforo forum! But before that, I have a question that I would like to ask.. Should I buy just license worth $140. Is it necessary to Xenforo resource manager? What is the use of xenforo resource manager? Does xenforo add-on (media/award/achievement plugin) needed xenforo resource manager? I hope someone could clarify these things to me so I could understand more.. Thanks alot!
