At first I did have problems figuring out how to use it. I don't see a "copy/paste" button and wish there was one. Overall, as I start to use it more and more I am liking it.
Regards.

So far, so good. Nice feature that long ago MS in word offered something similar. If marketed correctly, it should be very successful - God willing.

This system is amazing, but I have trouble with the 40 per month fee, but I will notify my supervisors at the business, it would be a great investment for the company as a whole.

Love it
I love it and have recommended it to friends and collegues.
Love the ability to change forms around and manipulate the forms to move entire sections around and still keep things neat and professional looking.
The dashboard is messy and not as well organized as it could be.

User interface can be better
This is a pretty good website to merge pdfs. Overall has everything you need. I do believe the user interface can be easier to use for those who aren't as tech savvy.

It met what I needed but there is a problem with text fonts. In my case I needed a specific font and I couldn't find it, it would be interesting if it were possible to include a new font.
