First of all, I like everything that's going on. Some good ideas are getting implemented.
So was any decision made on how stuff gets submitted (FIX/ENH), then included?
One idea that I didn't see mentioned (but I might have just missed it) is to add a ForInclusion project to sources.squeakfoundation.org, with write access for everyone (or Apprentice and up, or whatever). Announce that that is the place for code to be submitted, when (the author thinks) it is ready for inclusion.
Then harvesters would simply merge stuff from that repository into the release repository.
Then whatever tools get coded for improving awareness of new code in an MC repository automatically apply to the harvesting process.
