Seems user friendly for the most part. It would be nice if the documents could be automatically opened in Drive without all of the signing in process each time

The only reason my rating isn't a perfect 5 Stars is regarding getting an a document notarized online. Your website says it will be at no cost. But when linked to the vendor notary person, she said the cost is $25. When I contacted your company a couple of times, it was indicated someone would get back to me w/ answer. But that never happened.
