The flowfunding mailing list has not been active for a long time now. It was created to serve communication needs in the context of a particular past grant, and was not really used even then. At this point, it's just a spam target. As one of the list admins, I request that it be be closed. IMO, there's no need to preserve its (tiny) archive, either, but if we keep everything as policy, that's fine.
The list is here:
