heirloom seeds...discussion, trade, favorites. lets talk about em

So after growing a garden for the past couple years I have discovered the fact that you can't just save any old seed out there anymore and that you need heirloom seeds in order to save the seeds. seed companies use microwaves in their drying process that make the seed sterile so they can only be grown once. I have recently discovered a seed swaping web site that allows trade of these heirloom seeds for free called www.heirloomseedswap.com . but I was curious if anyone in here had any they would be willing to trade?

I also discovered a squash called vegetable spaghetti last year. when boiled the insides are long strands resembling spaghetti when cooked. i bought some of those seeds to grow in my garden this year. if ya have never tried it i would recommend it. I haven't been able to finnd an heirloom version of this which i am looking for if anyone has any idea of this let me know thanks. I'm also lookinng for some heirloom jalepeno seed.
