Keeping this info handy... I'm sure I'll need to fax my signature somewhere someday.
"An online service, Hello Fax (http://www.hellofax.com/), keeps a digital image of your signature on file, which you can then position and resize onto any document you upload to the service. Once the document is “signed,” you can e-mail it or send it to a fax machine from your PC. The service can also, for a fee, provide you with a fax number. Incoming faxes can then be viewed — and signed — onscreen."
