This proved to be a useful topic, thanks @thompsone
Though I got a question how should the code look so that the advertisement code would also include the ad appear in the TOPIC VIEW of a certain FORUM ID too. I mean to show ads on the top of the page when viewing any topic that is within a forum which ID is for example 55, 65 and 75?
I've found this post but I don't understand enough to make it work.
@newbie LAC, @opentype any ideas guys? 🙂
