To help people understand that they can actually improve Python docs themselves, how about the following changes:

http://docs.python.org/3/bugs.html - rename from "Reporting Bugs" to "Dealing with Bugs".

Explain that sometimes fixing bug is easier than reporting, because it involves less time from all people in total. Link to step-by-step documentation for the process and include channel for proposals how to make the process more streamlined.

Add links to archive and docs@python.org mailing list info
http://mail.python.org/mailman/listinfo/docs

On this info page make it clear that "Python documentation team" is not a team in common narrow sense, but a group of volunteers open for everybody. Either by providing a link to team page with listed members, or by replacing the text:
- "Mailing list for the Python documentation team"
+ "Mailing list for people collaborating on Python docs"
