Well, if you want to start in the style of Pete Seeger, you can buy his book, which is how many of us got our start back in the 60s. Nowadays there are helps that we never even dreamed of back then. If you check out
Homespun tapes you'll get the idea. They will be happy to send you a catalogue.

The usual disclaimers apply, and Homespun is not the only source, by any means.

If you want a banjo forum, try
BGRASS-L@LSV.UKY.EDU or BANJO-L (can't find the web addy, sorry). Try also the YAHOO groups.

Welcome to the ranks.
