Hi, i've not seen any popup.
With this topic, bub2000, KathW, and VTOLfreak have demostrated that such invasive type of advertising.

Personally, I prefer cool/soft/interesting banners. If some of them seems to bring something that I may need, I can click anytime. If I wan to support the forum, I can click on any of them.

I think this may be some way to solve the problem.
