That's an awesome idea!!! I mean, now with the whole revamping of the in-game mall, this would really work well. Karma for the brainstorm
! Here would be a good place to put it so that there can be some suggestive discussion on it. I'd say repost it in the Suggestions Forum
when you get the idea pretty flushed out, but it seems there's little to discuss. It's pretty cut-and-dry.
The only way someone would be able to obtain one in the first place would be to buy it with AP so AGE still makes the money. By doing it this way, it would probably promote more people to buy them since this seems to be a pretty safe trading method. It will also help make sure the person intended to get said upgrade gets it and doesn't get scammed by a look-alike. You send it directly to the person.
