A forum I have enjoyed is Pigs2Twigs site, most members are in the U.K. so you can talk stones and Km more easily. Plus the recipes are usually metric.

I read "Neris & India's Fool Proof Diet" back in 2008 and that's the forum that developed from their work. Now I'm a bit more comfy with a forum on this side of the pond, as I am in Canada.
