Walter-
It may look an good idea to create an new special list for this. But the reality proves that topic specific lists are not very successful.
Not much used http://mail.wikipedia.org/mailman/listinfo/wikilegal-l
That's because the word "legal" scares people.
absolute failure http://mail.wikipedia.org/mailman/listinfo/announce-l
That's because we have no rules for making announcements, nor a staff of volunteers who has pledged to do so.
The foundation-l list is necessary because wikipedia-l is clearly the wrong place to discuss 1) Wikimedia organization issues, 2) possible new projects and other tasks for the foundation.
On the other hand, I'm strongly in favor of merging intlwiki-l into wikipedia-l.

Erik
