Hello!
I also run a local community website for the town of Hounslow in west London (http://www.hounslowtw3.net). I have put eBid banners (we need some new ones guys!) and the Search box that's been provided on these boards on the Classified Ads section of the site.
I've also introduced a section for local groups (a kind of yahoo/google groups) and the first one is a local community eBid group for residents with eBid stores. Hopefully all these will sent a few more punters this way as the site becomes more popular.
