I have terrible handwriting and often end up having to tear up forms and fill them out again. Especially if the spaces provided to write information are small.

it's pretty good. sometimes when you edit, it looks like your edits are going to look funky, but when you print it looks alright. I wish it matched the text font and size as the original. You kinda have to hunt around and size accordingly

I made the mistake of subscribing to a… I made the mistake of subscribing to a year subscription with annual price due at sign on. I only wanted to test the site and see if it was right for me. I noticed within a few hours what I had done when I checked my banking account. I got online with their live chat support. I talked to someone named Sam and within 5 minutes, Sam had fixed my account to only a month subscription, refunded me all my money minus the monthly subscription. My mistake, Sam fixed immediately and was so nice and helpful. Great customer support!
