Okay, I must be using the wrong template name. Would somebody point me in the right direction? I have a 728x90 leaderboard in my ad_below_top_breadcrumb template but I don't want it appearing on the page where people are posting a new topic (create-thread) OR doing a full reply (ad-reply).
3. How can I find out which template to edit?
Using your browser, view the page source and look for a line of code near the top of the page which begins <div id="content" class="; the class is the name of the template. So for the main forum page, the line of code is: <div id="content" class="forum_list">, which makes the template forum_list.
My leaderboard is actually a Google Adsense ad. Can't that be hard coded as a responsive ad? Right now I'm just setting up everything the way I have it on my vBulletin forum and figured I'd switch everything to responsive code once I saw everything working properly...
