I cant figure out a good place without everything looking 'broken' or out of place. Have you guys found an area on the xF default skin that accomodates it well? (aside from the very bottom, looking for somewhere on top)
Ours is below the breadcrumbs and fits pretty well. We're on a 1000px layout. It's not live yet though. I found being above the breadcrumbs looked awkward and out of place - it fit quite snug under it with the sidebar still next to it.
Still gotta do some playing around with adspots before we move over though.
