I am beginning to think I am the only person in the Evansville Indiana area !! Feeling a bit lonely . :^(
The Indiana section doesn't seem to be very active in general, at least since I have been on here. For your question, I may be able to answer part of it. I believe FAN is Florida Aquatic Nurseries, which is a large supplier for plants that ships to retailers and other suppliers. That is my best guess on it, so maybe that helps. Sorry, I am far from Evansville though.
