Hi Jennifer, there seems to be no (public) mailing for Galaxy admins - where should such questions go? The public dev mailing list? We're also looking into setting up Galaxy at our institution, but my questions revolve mostly around manpower.
The galaxy-dev@lists.galaxyproject.org is one way to reach other admins. So is the IRC #galaxyproject channel (for quick Qs).
When the reply above was written (in the long long ago!), GalaxyCzars was just getting started. The group is called Galaxy Admins now. The focus is for those running public Galaxy servers and the issues they encounter as a group. There is no specific email/IRC for it - the dev list and IRC are enough. Meetups noted here: https://wiki.galaxyproject.org/Community/GalaxyAdmins.
Thanks! Jen, Galaxy team
