mjkgquilt - I think that it was the question mark that I clicked on (next to the x n upper right corner of ad)and then the next page stated either "unsubscribe" or "opt out" and I clicked that -so far it has worked to eliminate the big ad that was popping up in the bottom left corner - covered part of discussion thread.
Hopefully it wil be gone for the long term but I wouldn't be surprised if it comes back n a month or two. LOL the name of the game for free site use is to have ads to "sell, sell sell"
