I'm forwarding this to the mailing list. That's a better place to ask questions: I'm just one person, currently in the hospital with my son who has Cancer; the list has about 1,500 subscribers so the chance to get an answer is much higher. Signing a document multiple times involves that you have revisions. That's inherent to the concept of signing PDFs (see the PDF Reference). Each document can have one (and only one) author signature and multiple recipient signatures. That's how it works in PDF. You can have the PDF signed simultaneously by multiple people, and each time a recipient signs, it has to be done in append mode otherwise the previous signatures would be invalidated (for very good reasons: by signing a document, you change it). > i'll appreciate your answer!!, > > Best Regards, > > Juan Manuel Diaz > > P.D.: Sorry for my english. I was in silence for a long time!!! hehehe Don't worry: your English is excellent!
