I think your site is well designed and has substantial potential. But being unfamiliar with all the choices, my initial effort at using your site took a little longer that I had hoped it would. But that is a minor critique. i'll do more exploring at a later date.

So far so good... i've used several different programs and am a quick learner.... can't say that for a lot of people who are not used to new programs.... this is VERY user friendly and I will definitely recommend it!
Kate
What an awesome product. We use accord forms so often in this office that it is nice to have help! We like that most accord forms we use are already available from the site, but more so than that, the fact that we can upload our own documents as well. When you have to generate 150 certificates for one client, all different, this program makes that process seamless. The site runs very well, have not had to deal with freezing issues or losing extensive work because it didn't save, the site always saves my work for me. We just couldn't be more happy with the service. There is not a lot that we do not like about the program, but one thing sticks out for sure. If one of my agents is logged on to the site and another agent logs in, the first agent will usually be kicked off. This was not really even an issue since the system always saved the agents work, and all of my agents will announce now that they are logging in.

Thank You all the staff at PDF
