It is a wonderful program to use now that I have figured out what today. It is very easy to move around in the program too. Thank you for the intro videos too!

I had to cancel my subscription right after I got it (the first time) because we were told not electronic signatures. The customer service person I was connected to was very quick with applying my refund and explained the banks general policies. It ended up there was a mistake, so I'm back. I enjoyed the ease of using the product. I was able to pretty much teach myself how to use it. I do look forward to seeing what the webinar has to offer.

Definitely works. Not sure if there is a way to make figures line up just a little better or have calculated fields, but definitely better than just using adobe acrobat

The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?

The price should be mentioned up front. You have to pay at the end because the document is important. I'm sure that is intentional. Its a good program so far. I will let you know the final outcome.

I think you should ask me this again in… I think you should ask me this again in another month. I'm very new to using this, and far from computer literate, but so far I am finding it very easy & extremely useful. Thank you! Lisa Marie

It is a great tool that anybody can use It is a great tool that anybody can use. It does not matter what type of business, school, or type of work you do you will get out of this service if you have to continually deal with PDF documents. Do you need to sign something? Check. Do you need to change a shipping label by a major retailer for a return? check. Tax documents? check. For real, I'm just a regular stay at home dad and I use this AT LEAST twice a month.

Having better results with the site It is a lifesaver as far as my clients being able to sign consents on the screen and get them back to me. So far, the recipients of my docs have been able to follow the instructions and sign the docs without difficulty

Its great overall for all the services… Its great overall for all the services but hated the part where it reveals at the end that subscription is a must.

Microsoft Word allows you to keep the header information from each of those separate files through the use of section breaks. Section breaks are the key to keeping the headers intact when you insert a document. If you use a page break instead, Word will strip the headers from the inserted file.
