Are you continuing to see pop up ads? Do you see them when you are accessing the Forum through your mobile device or your desktop machine? We are constantly battling this issue. It more common when on a mobile device. If it happens again please screenshot it and sendme a message.
No mod or admin on here has any ability to get rid of the ads, but you do. download Adblock Plus. it's free, installs in less than a minute. I haven't seen a pop-up ad on the internet for years. It works.
