No, R.S.U slash Unicyclist.com is not some magical bat-signal that will summon all unicyclists within a certain geographical region within the immediate 24h period afterward 
There are riders near Jax, I know… check the First Occasional Florida mUni Meetup thread for some possibilities, but not everyone in any one location posts here, and even fewer of those follow things religiously.
What kind of riding do you do now, and what kinds of riding would you like to do? That can play a factor as well, though I don’t know as much about the panhandle as I do my own neck of the woods.
Good luck, in any case… and keep us posted if you do make the move
