I re-read through my post and I don't want it to sound like I am trying to bash UBBDEV, and if it does sorry that was not my point.
I just thought maybe we could share idea, to help everyone at least cover there hosting charges.
"you could make the same amount of money in banners at the top/bottom/side of your forum"
I have not found that to be the case at all, my one pop-up with a 24 hour period, makes about 3 times as much as the top/bottom banner combined.
And no my host does not make me use pop-ups
