I have seen alot of scripts and posts about placing an ad based on counting the number of posts that are printed via the loop.. (ex: every 2 posts.. etc)
What I would like to do is have an overall count, not just page specific... For example, since my blog only shows 10 posts per page, and I wanted to display an ad every 15 posts.. Is this possible? Is there a way to count from the beginning of the first page back?
