Great idea. Could you also please make a system adjustment that the thread remains visible to unregistered guests? Otherwise a lot of information becomes suddenly inaccessible for many people.
An alternative solution suggestion: Give half-mod rights to any interested and established teacher with good reputation, and also give them a shared sub forum where they can manage threads on their own teachings. Call the sub forum "Sifus Corner" or something similarly suitable.
@zen-bear, what do you think?
