I've been editing the first post of my "IPSF Strombus" chain to track who got what from whom. That way someone can, at a glance, see who needs something that they are ready to frag. I think only the original poster can edit their own posts.
I neglected to put the DATES of the hand out, which I think might be a good piece of data too, so we can see, on average, how long it takes for a piece to be "frag ready" or even track growth (assuming you give out a piece the same size as you got, or in my case, how long it takes snails to reproduce and grow to shareable size). Actually, it was the date of the "clam talk" meeting.
Are we tracking location as well? That seems like less useful data, but it might be handy for matching up donors and recipients.
