Colette W
I couldn't print directly so I followed instructions for converting document into PDF file on my computer - smooth sailing after that. I like the paper trail of all activities with forms - very helpful to review My Account and see what I have done.
Great service! Could use some updates though. The site is rather slow at times, and when changes text size there seems to be a bug where the page needs to refresh or reload. Also, general improvements on loading time would be nice. Also, please make the process of saving to PDF less steps and less clunky. I don't need to be shown where the pdf will be once downloaded.
