I like the program. I did pay for it, so I feel that I should be able to upload pictures to the file. Uploading images should be included in a basic membership. I still like the service.

Incredible Customer Service
I had an issue with my membership and they cleared it up and gave me my necessary refund within the hour. It was incredibly quick customer service. I also love the efficient services of the site.

Very easy to use, being an assistant and constantly filling out reports for the State, it is nice to have something that works so easily and is consistent in its responses.

Not your fault
Not your fault, but I need my "original signature" on the form for the form to be accepted. I was sooo excited that, during this whole COVID-19 isolation I could get this document notarized here! Ugh... Ridiculous. I may try it anyway as the delay in getting this done the way their website says they want it will be more ridiculous after my quarantine....hmmmm
