I think that both a time limit ans post count limit should be required.
time limit because some people post 100 posts + a month. but 1 month into this you just aren't knowledgable enough.
post limit because someone can join and never paarticipate then start selling a few months later wiyh that I'd.
I agree that the benefit of our BST forum is that a new person can feel safe buying here and know what they are buying is as described. without the knowledge to state those about your item its just like an buy it now on ebay.
I think a minimum of 2months and 50 posts is not asking a lot.
lastly, I think good bad ugly razors can all be sold here. just take good pictures and state the facts. I've pm'd sellers calling things mint that had obvious rust all over it plus hone marks. shiney does not mean mint!

ps. I don't think I sold a razor on the BST forum till I was a member for over a year
