This forum has some very bad pop-up advertisements. They faked adobe-flash player and asked me to downloads stuffs. I only see them when visiting this forum on Safari browser. I wasn't going to say anything, but since you asked.
Forum Administrators, I understand that this forum needs advertisements to run. But, if you aren't careful with what content to show, you can give hands to the bad people.
I use safari and don't have any problems. In the past, there was a popup which insisted to install Mac cleaner (false). I wrote two times to the forum administrators about this situation and now I never have any problems.
