Tex123, I'm sorry you find the Ads a nuisance, and I have to agree with you. However, the Ads pay for the Crossword Solver site which makes it possible for Ash to provide a Forum which is free. It's not too difficult just to scroll down past them.
Ash changed his Ad suppliers a little while ago and this is the source of the problem. He is contacting them to see if Ads can be restricted to the sides of the page, rather than in the posts themselves.
