KINDLEGRAPH is new. You may not have heard of it, but it’s a MUST DO for published authors. Here’s why:
1) It’s free
2) You can do this, in less than 15 seconds from your laptop at home at any reader’s request:
Yep, they buy your ebook.
Then they request an autograph.
You type a message which comes out in handwriting as shown.
You sign with the mouse. (I’m sure my signature and yours will improve with practice.)
You send it.
Costs you nothing.
Gives them the chance to have what before only hard copy owners could.
It’s a win-win for everyone and if you’re a published author, it’s a no brainer, you need to sign up. Go to http://www.kindlegraph.com/ and click Author’s Sign-up here! 
Any questions? Seriously? Why wouldn’t you do this?

Well, just gave it a try…
Is it possible to sign with a stylus on a tablet instead? Might get a better signature that way.
Not that I know of at this point no.
Hhmmm… does this only work on Kindle devices? I don’t own one and I don’t see any way to figure out the send-to-kindle email address for my Kindle for Android and PC apps.
You can sign up at Kindlegraph and have it emailed as a pdf to you and then put it on your computer anyway. I would have to at kindlegraph.com for more details.
