Not sure if you have done this, or are working on something like it, yet, but...you could come up with a "popular" questions/answers list and post it on the first page of this thread. That way people have an idea that no question is off limits. Plus, you could ask the group here who has suggestions/ideas on specific topics, that way you could add their name to the answer portion and visitors could get an idea of who to speak with regarding that specific topic. i.e. Herbal Remedies = Ann or Victoria, Writing = Beth, etc.
Just an idea 
I think it is a great idea.
we can work on this tomorrow.
and you are right. no questions are off limits here for our diverse staff of worldly scholars.
