It's funny, I've seen my Wiki maps pop up all over the place, including in one of my university classes (a professor used a map I made on Wikipedia in a lecture slide).
And as you know, I'm happy for any of mine to be used by anybody, without the need for attribution (and you know this since I've expressly stated as much for your use on your website).
Incidently, I'm working on a post-redistribution map of the provincial legislature ridings of Nova Scotia presently.
