I love the site, I don't like all of the pop ups though! I constantly have to click out of the pop ups when opening a new form. That is my only complaint! But, all in all, I love this site and it helps me be more efficient.

Great product but some features were clunky for me during the trial period...specifically send to sign. Hoping for smoother usage with the purchased professional version & after attending the training webina

Love the software but a bit of a brain surgery to start with each new document. The links, steps and path for loading and working on documents need to be highlighted better for new users. Probably makes great sense to the programmer but new users have to hunt for the next link or button to click.
