That's too bad, although I can see Adobe's reasoning. 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!
