I just purchased PDF Studio Pro for personal use after spending a couple of days extensively trailing a whole bunch of other similar software. So much software is offered without a user guide, depending on a “knowledge base” to help people learn.
I’m also impressed with your online user guide, as well as the multi-platform support. I just want to say how pleased I was to see how much substance you put into your software. National Oceanic and Atmospheric Administration (NOAA).
