I offer my assistance also. It would require the article you mention to help clarify the functions/roles of the different admins, imo.
Apologies for the double post. I will be happy to write this article as long as it hasn't already been written and as long as I can contact all the admins to get their feedback on what they do. Perhaps I could ask everyone to send me a job description and then compile that and invoice it under "collated." How does that sound?
EDIT: or better yet, create the page with a headline for each admin and ask them to complete their job description, then I rearrange order to have a logical flow. And I don't necessarily need to invoice the page at all since it would be a total community effort.
Thoughts?
