PC, I don't know about that, but if they were, suggesting that people click on them just for revenue would not be good- like cheating- and could create problems with our advertisers. I'm not even going to GO there. So just continue on as you have been; if an ad interests you, by all means visit it! There are some good vendors represented, who I have happily used myself in the past.
Anyway I think this thread has pretty much fulfilled its usefulness... I'm going to lock it now.
Be positive everyone!
