That would be doable.
Still, it's annoying that I completely spaced on getting that in. They are, however, gracious enough to give me a week's grace, when I said that I'd sent the check in, so they've marked the account to give me the time, since I sent them a letter saying that I really wanted to renew.
I'm glad they are that good about it. It doesn't stop me from worrying, though.
