Seed Club

I tried to start a seed club at work, but wasn't too successful.  I envisioned us sharing seeds -- I'll trade you 3 butternut squash seeds for 5 buttercrunch lettuce seeds.  I got a bunch of people interested, and wanting to participate.  I created a google document, that could be shared among all of us, and I got a few people to list their seeds on it.  I thought we could all reference the document to facilitate a trade.

I just couldn't get people to actually do it.  For starters I had quite a few seeds available and a lot of the other folks had only a few seeds to share.

Has anyone been successful starting a seed club?  What's more important?  People who are really into it?  Or people with alot of seeds?  Or both?  I don't know.

I think it'd be lots of fun (and would save some money) to trade seeds you don't plan on using for seeds you really need...

FYI, my favorite seed store:  Victory Seeds
