Judy, Rick, and everyone else, Trish recommended that I post my idea in the Site Talk forum, but I wanted to share the link with you in case you never visit that forum (I don't visit it often, personally):
The thread "ATP Annual Seed and Plant Exchange Idea" in
Site Talk forum
Please let me know your thoughts about having a large, ATP swap.
Rick - as for the seeds you had with no takers, you never know...there are new members here on ATP all of the time and if this were made into an actual event that had some amount of publicity on the home page, I'm almost certain you would find some takers.
Making it an event is what is important, though. Otherwise, someone who would be interested in your seeds has to stumble upon the right thread in the right forum (at the right time) while sifting through the multitudes of threads that there are to read. Marketing is everything in this situation. ;) We really need it to be an event(s).
