Could it not be made so when someone lists an item in market it comes onto the forum as a new post?
I'll see if I can work out how to do something along those lines - but I suspect it won't be easy, so it may be a while. Meantime, you can do as you did - post a message here.
That's very weird - I worked on it yesterday but, far as I could see, hadn't fixed it.
