I had a problem with a pdf file freezing up on deadline and not being able to copy it when I was on deadline. I have to say, though, your online customer service was extremely helpful in solving my problem.

The support team are the BEST! The support team are the BEST!I didn’t understand that I was signing up a yearly subscription. I wanted to use the pdf only once. I notice in my account they charge me for a yearly subscription. I contacted the support group, explained my problem within minutes they solved my problem and refund my money.Thanks again for a Great job!!

Filling out forms has been so easy and time saver. Filling out forms has been so easy, best part is that I can edit and save in Adobe or PDF form. This site is great and inexpensive.

Making signing easy It was a great team friendly program that made things get done a lot faster and more efficiently even in large with large numbers working on the same thing. Makes getting multiple groups of people working on one thing done faster with not all having to come to the same place. Sometimes it was difficult trying to download the papers once the words were added.
