HiI think I may have had success. I often say :
"Its this great resource on the internet where loads of singers and musicians discuss folk music from around the world"
I then go onto say:
"You can start threads or input ionto threads one many topics like getting song words to adviceing someone on the best guitar to buy"
Than I finish off with :
"The address is www.mudcat.org"
Ok so I don't say it like this every time but thats my sort of formula, brief to the point and it explains what its a bout. OK there is loads more I can say to but a non catter member I recon that all they need to know.
Cheers, Sam
