have you checked out the current seed exchanges here? You can still get in on

WLOMWL Swap (What's left on my wish list) and Gardeners Favorite, Veggie Seed Swap I think the cut off date is the end of the month for both. http://forums.gardenweb.com/discussions/5015667/wlomwl-swap-rules-and-wish-lists?n=18 & http://forums2.gardenweb.com/discussions/4963689/gardeners-favorite-veggie-seed-swap#21326014

oh and you will need to set up a profile the on the left hand side menu, go to the advance settings (towards the bottom of that page) you can put in your growing zone & the seeds you are looking for as well as seed you have to trade. This way you can send & receive msgs too.
