Need to modify ad after first post, but forgot how I implemented it :(

[carolc]

I've had an Amazon banner showing after the first post for quite a long time. But since Amazon dropped their affiliates in my state, I need to get rid of the ad and put in something else. But I can't remember how I put it there. I didn't seem to modify a template (searched templates for "amazon"). I use vb Ad Management, but I can't seem to see where it may have let me add a banner in this location. It is possible that I modified a file, but not sure what file I would have modified. It is a table with "Sponsored Links" as a header.

Any ideas?

Thanks
