General thoughts about writing GW's: Think about what you're trying to do --you're trying to get a busy person with some decision-making authority to look kindly upon your situation and cut you some slack.
So make it as easy for them as you can. Typed, lots of white space (small paragraphs), no accusing or angry noises, ask in the first paragraph and again in the last paragraph for what you want them to do.
I wouldn't worry about typing your signature. This isn't an adversarial situation where you're worried about them falsifying your sig. (It's a groveling situation!

) If you're a little twitchy about it, type the "yours truly", hit return 4 times, type your name, and scrawl some mess that you never, ever use as a signature.
Also, don't send it CMRRR. Think about how you feel when you have to sign for a little envelope --usually defensive and angry, and maybe a little scared. It's not like you're going to sue the creditor for not responding to your GW, so you don't need proof of receipt. Although it would be awfully nice to know, lol.
* Credit is a wonderful servant, but a terrible master. * Who's the boss --you or your credit?
