Well, the recipients of the zillion letters wouldn't know my signature from anything else, so you might as well forge it if you're going to do that. As I understand forgery (and I don't, very well, other than having had someone steal checks from me and forge them a long time ago), a signature is only your signature if you say it is. That is, if I have a proxy sign something, I can later claim that it's my signature, even if it's obviously not, and there's no forgery involved. It's tricky. That's why they have witnesses and notaries public for things that really matter, so you can't claim later that it isn't your signature. Anyway, given that it's trivial to take a real signed letter and digitize it, no matter whose signature is on it, it isn't terribly risky to digitize your own signature and use it for your own form letters. If someone wants to forge your signature, they're going to forge your signature, but it's a felony no matter how you slice it, and the small matter of who digitized it is not likely to bear very heavily on the matter. I'm no lawyer, but I just don't think that a great deal of paranoia is in order in a case like this. As the original poster pointed out, it saves them lots of time and money to be able to print the signature on the page with PostScript instead of a second pass through a photocopier, and forgery is, let's say, a minor issue, not a non-issue. -- Glenn Reid RightBrain Software glenn@heaven.woodside.ca.us NeXT/PostScript developers ..{adobe,next}!heaven!glenn 415-851-1785 (fax 851-1470)
