It's official: I've changed the patch submission guidelines (http://www.python.org/patches/) to point to the patch manager at SourceForge. We are no longer bound by CNRI's legal department, so the requirement for disclaimers or wet signatures is gone.
We'll have to see how it works in practice. I've set the address where new patches are mailed to email@example.com; this should send notifications to the patches list. We could change this to python-dev perhaps, so we can retire the patches address completely (giving it an auto-respond pointing to the SF patch manager, as barry suggested).
There are several tasks to be assigned now: we need a triage person who should go through the list of new patches regularly to assign them to developers; we need developers who are willing to have patches assigned to them.
We also need a consensus process to decide which patches will be allowed through. I'm hoping to experiment with SF in the coming days to come up with something.
Finally, we still need to do something about the existing backlog of patches. The PythonLabs team will try to do something reasonable here.
This is not the end -- it's the beginning!
