I have a huge gripe that drives me nuts. Does no one use the address in your transactions or perhaps not know it is there. I have mine listed but it seems like I still have to send it via pm to most of those I have a transaction with. Many times I go in and the other person doesn't have theirs listed. then I have to send a pm and wait for a response. To me it would save so many people a little time if they would list theirs and look in the transaction for the other persons. Instead we have to exchange addresses via pm when the site provides the feature for us. There's my gripe. Time to move on.
