Market Farming

["TxBeeFarmer" <TxBeeFarmer AT HotPop.com>]

Ok, now that I know organic is desirable, but not "required" to be a CSA
farm, do I need to join some sort of government group or have some sort of
certificate or license to be a CSA farm?  Is there a master list of
"official" CSA farms, or are they CSA farms just because they say they are
and post their name on a web site?  We already have a Farmers' Market group
that has become a nonprofit organization, of which I'm on the board.  Can
that group be a CSA group somehow, being the focal point for farmers and
businesses to get together, or does it have to be by individual farms
working independently?

Thanks
