I'd recommend taking the DBPR-approved course for directors. A signed statement is also an option under FS 720 but at least a couple of FL attorneys say to stay away from it.
From
http://www.hoa-condoblog.com/EGBlog091018.html "The law actually allows you to sign an affidavit which basically states that you have read your association’s governing documents"
and
"Many of you have illegal provisions in your governing documents. Your affidavit apparently requires you to promise to uphold these provisions even if they are illegal and unenforceable. Worse yet, the affidavit does not even require you to read or even acknowledge Florida Statute 718 (the condo statute) or Florida Statute 720 (the HOA statute)."
Another article references the above attorney's opinion at

In any case, the statements and course-completion certificates must be on file with the Secretary. If you really have none then I suggest you get them tout de suite. If all directors have been in office for 90 days and you don't have any on file with the Secretary then, according to FS 720, all of them are suspended. They can get un-suspended by filing a statement or taking a course and submitting their certificate.
