I thought/was hoping that it was a simply not-yet-implemented feature and not something Adobe Acrobat and Adobe Reader specific. Well, it was worth a shot. Anyway for signing PDFs myself I still use and prefer JSignPDF: http://jsignpdf.sourceforge.net/ That is really neat and supports a lot of very helpful features (like visible signatures). It's just that it isn't a solution for general forms that others should sign, since not all of them are technically versed or willing to install some third party program. That would have been a good use case for ready-made PDF forms with signature fields. Thanks for your answer! -- Best Regards, Andreas
