Welcome to WebmasterWorld Guest from 184.108.40.206
The problem is, in the threaded view of my forums, there's only one page, and if you click a message that's halfway down the thread, you're automatically scrolled way past the ads and never see them...
Also, just to be clear: I would NOT wrap the ads in code that keeps them viewable no matter how much the browser scrolls - I only want to place the ads at the location the user is FIRST viewing, so that they're visible, but not annoying.
I belive it is alright to use the ads on forums.
I am not sure about this one, but my instinct say that it could be against the google policies, though not exactly defined.
However, perhaps it may be alright to do so. So the best way would be to contact Google to get an official answer.
Basically, you'd just put the AdSense code in a <div> and use CSS to modify where that <div> is allowed to go. I don't think they have any control over that happening.
