The attached "Final draft" patch is the version I plan to commit tomorrow. Major differences from the previous draft:

* accepted MAL's suggestion of using alphabetical order
* as RDM suggested, explained the rationale for the cases where we encourage people to participate
* after fighting with ReST trying to get it to let me have an indented paragraph following a bulleted list, I eventually hit on the idea of using the "topic" directive to separate entries from each other without introducing an ever expanding list of TOC entries on the main page
* there are now more extensive guidelines inline in the doc as a ReST comment
* three cases of "acceptable links to include" are covered: personal sites, commercial contact details, and crowdfunding
* questions and suggestions (including for new categories of acceptable links) are explicitly directed to the python-committers list

Given the useful feedback from MAL & RDM, I'll hold off on pinging python-committers again until this initial version of the page is live.

Does anyone else want to provide an entry for me to include in the initial commit? It would be good to have a couple more initial entries to help folks generalise from the available examples.
