The mailing lists are for policy nerds, techies and masochists. Article- related discussions already take place on the respective talk pages, and for user help there's the Village Pump. I've already stated that I agree the discussion system on talk pages needs improvements - give me money and I will fix it.
Heh...give me an admin account and *I( will fix it.
Define "admin account" and explain what you want to do with it. Set up a PHPBB? Yeah, right. If you want to improve the Talk page code, go for it:

We await your patch at wikitech-l@wikipedia.org.
