@rockpile, the system doesn't allow anyone with a zero quantity of seeds to dib. This would be easy enough to fix by having them put in a mock pack of seeds:
I'll be taking what doesn't sell in this swap and putting it into one of the swaps later this season. I'll add in some new varieties for people that played in this swap so I have offerings for all. If I still have leftovers I offer on Facebook.
I don't plan on hosting any swaps again until next season. If you wanted to host you could make a post and see how many people were interested.
The other option if you're looking to get rid of your seeds is to make a post in the seeds forum looking for a newbie. They could send you postage or you could just send them to them whatever you chose.
