I don't want to offend anyone, especially since although I have often perused this thread I've yet to be able to take advantage.
I think both Woodstock and Corso have a point.
I think previously some people have been too quick to voluntarily change an offer on display or maybe pressure another to do so. There are some members who only come online once a week or less, it wouldn't hurt to give some offers a chance at being taken.
However I also think that the thread in general is remarkably self regulating. It doesn't really matter how good or poor an item is, the worth of the item is to the person who wants it. If nobody wants an item that's put up then really it doesn't matter how good it is, it's worthless with regards this thread.
Also IMHO if the thread dies it will be the fault of the last person to post something up that nobody wanted... Not the people who didn't want the item on offer.
Best of luck.
