bmac, I filed to create an LLC last week (more about that later), and I've received two letters now telling me about more forms I need to fill out, with associated fees.
They're scams, as it happens, but they're damned good scams. They look very official, and I've already filled out a bunch of forms and paid fees, so what's one more?
It was the second one that tipped me off that something was wrong. If I'd only gotten one, I might have paid it. Damned insidious, and so fast, too.
