I have heard quite a few times before that it has been a problem with people buying a friend slot on accident. One click and you automatically lose 500FG. This is just about $18 worth of Forum Gold if you donated for it. Just a few minutes ago, I would not have made this mistake if there was a pop up that asked for the approval of buying a new friend slot.

It's simple enough and would save, I'm sure, many people on wasting 500 FG.
