That's another swap paradigm!
Everyone sends spare and old seeds to one person, often with dubious or ambiguous common-name-ID and unknown purity and age. Purely volunteer.
The central person then sends out 10-20 pkts to new members willing to pay postage for old seeds and only limited ability to select what they get. I gave up on that when I saw the common names only narrowed them down to multiple genera and dozens or hundreds of species.
And some of the re-traded pkts were clearly MANY years old, but you didn't know if it was 5, 10 or 20 years.
That was also when I learned to distrust "OP" printed on a seed pkt. It might mean "OP - a stable variety and I'm hinting that I MIGHT have thought about isolating it at least a little", or it might mean "the wind and the bees pollinate my garden and I want to hint that maybe I don't isolate varieties with space or time of flowering".
The dual usage causes it to mean nothing unless the trader spells out with words which was meant.
