[Mailman-Users] External membership sources

[Tracey McCartney]

The Mailman home page thanks control.com for their sponsorship of, among 
other things, "external membership sources" in the new version of Mailman.

Is this "external membership sources" feature documented somewhere yet, and 
can it be implemented by list administrators, or is it available only to 
the folks who have access to the server Mailman's running on?  Our Mailman 
lists run in a shared hosting environment.  I'd love to be able to run 
Mailman from a MySql database so that I don't have to keep up with 
subscribers in two different places.

Thanks,

Tracey
