I was excited that I’d be able to do this, but the script has flaws that make it unusable. It looks as if the offered ot for free just to advertise the pay versions. But if they’re going to put flaws in a released version I wouldn’t trust a pay version, either. I may think of something else, perhaps just a board for that purpose. I used to do a lot of buying and trading off of an online bulletin board called Tulsa Trade back in the early to mid 90’s. It simply worked by allowing people to offer what they had and hash out the deals there.
