1. it requires three step subscription process

2. it is impossible to post a reply to existing thread/idea

There is a web-interface in Google Groups at https://groups.google.com/forum/#!forum/python-ideas that can solve problems above and provide some more nifty features such as embedded search.  But there comes another problem that messages posted through the group doesn't end in list, because list requires subscription.  I've already tried to find a solution, but run out of time, so I summarized the proposal at http://wiki.python.org/moin/MailmanWithGoogleGroups

I may or may not be able to publish outcomes of my research, so it would be nice to get some help in investigating the problem and publishing a solution on aforementioned wiki page. Thanks.
