Give me a break. Lots of yak for nothing.
A google search would have turned up the answer in the first result.

Print the form. Fill it out. Mail it to the Florida Secretary of State with a check for $35.00.
That is a deal. It costs $80.00 for the registered agent to resign.
Yes, send a resignation letter by certified mail to the registered agent of the corporation. You can have it notarized if you like to prove it is your signature and it was done on a certain date. Keep a copy for yourself. The date might well prove to be important to limit your liability when the corporation gets sued or prosecuted and the plaintiffs also name the officers as defendants.
If you are a board member, you will also have to resign from the board of directors.
PS: What kind of people do we have posting here? If you do not know business law, please go away and do not post in forums where you have no idea what you are talking about.
NO, you do NOT have to return your stock to the corporation. Absurd. Being a stockholder, assuming you are, has no liability issues and is a totally different thing then being an officer. Of course, I would recommend that you try selling your stock back to the corporation or the president to completely wash your hands of things and get out some money before the entire thing goes down in flames.
