I was having problems with not just completing the forms but also with abtaining my information, the young man with online chat help was such a blessing to me. Being a disable veteran some of theis computer stuff if a bit upsetting but Ralph helped me.

It is great! I would like instructions on how to save a blank form if you don't mind. I keep opening up the old form, then I have to delete data and replace it. Thank you!
Eden M
I love it for the most part. Just wish I could send a document to a person without knowing their email (ex. directly to their Facebook account) with the ability to view and sign not edit the document. Other than that, it's been great!
Akiaya H

What do you like best? Easy to navigate, loads quickly. I usually don't have a lot of time in the field to wait for loading. What do you dislike? Once I was proficient in the navigation, I was good. What problems are you solving with the product? What benefits have you realized? I get a fast turnaround on documents that need signed. I can also verify that the documents have been signed while out in the field.
