Hi Cadfael, Good luck with your new site. It sounds like a very interesting concept for a community based website. I like the idea of neighbourhood hubs. It could also be styled like apps. on the iPhone? [I hope Steve Jobs is not listening?]

The ad. space, I think a few people have already commented on. Couldn't you assign some of the space, on individual pages, to each district? So to free up some space on the main front web-page?
It'll be good to see a further mock-up, or trial, with some of the elements workings. That'll give us a better idea on how it will be used.
Good luck,
Daz.
