If anyone else is interested in seeds :) a couple of tips from Arjen at Emerson below, and the possibility of a workshop for saving and then swopping.... be great to get a lot of the community along for such a thing -"save money, swop seeds, eat well"
"I always save some seeds for the next years. This year is pakchoy (some sort of Chinese leaves) and probably soem flowerseeds as well. It is really important when seed saving that you do a proper selection of the individual specimens that you want to use for use production. If your crop is a cross-pollinator (most plants) then after selection you also need to isolate your chosen specimens from other flowers plants from the same species - otherwise the seed will be pretty useless and slowly, or actually rapidly, your variety will degenerate.
I am quite happy to put up an afternoon workshop about seed saving - some theory and some practical - if there is enough interest."
