Are there any safety tips that anyone can share with me when buying a used license. I haven't bought a forum license before and am looking to buy a used XF license. I have been browsing other websites for licenses and have seen a couple of sellers at where I was aiming price wise. I don't know how to tell if the license is legitimate, how I get member access here, or generally how any of the exchange works. Also, what payment method would you suggest using? Paypal seems the best bet.
