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.
