List seems partially active. As this is a project-wide list, we shouldn't really disable it anyway. Listadministrators seem inactive. Best to assign new moderators to deal with the work load of the list and ensure legitimate contributions are accepted.

16:15 < mutante> any volunteers to be mailman admins?
No response at all. As such, I am going to close the list [really unfortunate as it is a project mailing list] and if any one wants to administrate it, they can after requesting it be reopened.
