I'll give this a refresh for you fiddler. I asked a similar question at folkinfo a few days ago. The only other national site (there was a link to a local campaign in Devon) that came up was Action For Music which is included in the links from the site I gave you.

I too would be intersted if anyone can come up with any other sites as I'd like to be able to point people to the clearest possible source of information. The site I gave seems pretty good but it's quite possible that something better exists.
