I think it went really well too even with so few people. I look forward to participating in another one later in the year and hopefully I can add some new things. I've added some reminders to my Google calender about harvesting seed earlier in the season too. I usually don't get into "seed mode" until the fall and forget all about the spring bloomers that set seed in summer.
I'm curious was that extra name in the swap list someone who dropped out early or did they join just to observe how the system works?
