[Python-Dev] Proposed: change to posting rules for python-dev

There's been some talk off-list about changing the posting rules for python-dev, such that non-member post attempts are automatically rejected (i.e. bounced). This means you'd have to be a member to post to the list. I think that's not an inappropriate rule for python-dev. taking-the-pulse-of-the-list-ly y'rs, -Barry
