Subscribe to Author?
I had an idea...
You know how YouTube allows you to subscribe to a "channel" (an account)? Perhaps we should have that for our authors, or Ibl'ers or whatever we call ourselves. The Ibles Robot may be a bit busy, but his girlfriend/secretary might be willing to PM me whenever whoever I've subscribed to posts something new.
Kiteman had a good point: Make Groups subscribe-to-able
Just a thought.
