G'day yeehah, sorry you feel this way. The rule was brought in to stop "fly by nighters" coming in, off loading their stuff and then doing a runner. We would like to promote trade between hobbyists that can be trusted and who are regulars on AP. We chose 20 as an arbitrary number. I still think it's a bit low. I would like to make it 50 but 20 is a compromise.

20 posts really is not many. You'll be surprised how quickly you can make 20 posts. Give it a shot.
