We've got a couple weeks, Robin. Lynn will let us know how her colonies are doing... some may not be in good supply, but she may have others to add to the list. :-)
DND, Daniel, I hope you forge ahead organizing some group buys, either for in person pickup or remailing. Definitely anything dormant (or non-living, like Atlas gloves) makes for an easier experience. There have been many successful co-ops for live plants in the co-op forum at DOG (Dave's Garden, or "Dave's Old Garden"), but there have also been some disasters, and Daniel is totally right when he says problems get blamed on the host.
Hope the articles help... if I can help you out, just drop me a tree-mail.
