Lyn,
This is basically what most of us are hearing but they’ve also been willing to accept them directly over the phone as credit card charges. I was never told to mail the payments but it might depend on who you speak with or the timing of your inquiry. I believe they still have a mail drop forwarding address in Florida.
And as an additional thought, if you’re on Facebook at all, there is a FB group for friends of the Towers at Mullet Bay with information and occasional updates as to what’s going on there.
