I didn't realize how much use I would.

I didn't realize how much use I would… I didn't realize how much use I would make of this program, or the range of functions that it offers. I just got the free-version at first because I needed a digital signature. But now, as an academic, I find I use it all the time to share and to sign documents: now that everything is online and we have limited contact, this has become more important. I can't say that I've mastered or even noticed all the file features this program offers, but almost every time I use it I discover something new. Well worth the money!
