Well, other than the RVO link taking you to Orchid Bids, you are doing nothing wrong.
You are right, there is currently nothing for sale there. I just had 5 or 6 things for sale over the last couple of weeks. I will be posting some other things again soon.
You will be able to see the items for sale without paying the $1 fee, but will not be able to bid or list unless you do. It is not just an age verification thing, it is also a way to verify our reality too, a fraud check if you will.
If you are into paphs I can go post a couple of things right now!!! I also have some NoIDs if you like them.
