I may be an idiot but it isn't the most intuitive experience I've had. I have been under pressure to produce so that may have something to do with it.

So far, so good. I love the fact that, before I paid--my documents were always saved and not lost. So that later, when I was ready to pay, I didn't have to start over. That was awesome.

I have been using ********** and AirSlate for over a year now to create digital documents and digitally signable documents. The system is very user friendly and all the options to automate my digital forms are logical and intuitive. I highly recommend this product for creating digital forms.
