If you're going to go for anything, I'd recommend, as already suggested, that you go for a VISUAL aid, like a map, of the general area, divided into regions and "hot spotted" so that you click on 'em to see who lives in approximately that area. You really DO need to keep it simple - especially if you don't want to frighten off poor little non-academic types like me.

There's already an enormous amount of text based information at AW - you really could do with more graphic based stuff instead.

That said, I STILL feel this is all pretty unnecessary!
