I use adblock plus, and it is a great extension. This forum on the other hand has problems. When browsing this forum, I have received numerous error messages from the site itself. In addition, someone seems to have posted an unrelated link in this very thread.
It is very well hidden, but if you hover your mouse over the second period in that post, you'll see the link. It is possible adspam.
Other than that, the site is set up fine. If I need support, I know where to post. Each forum category is clearly set up.
