Overall a good experience. Sometimes the lack of features like aligning fields (i.e. Publisher) is frustrating: the ability to copy details from one field to another (drop downs and field attributes) making some forms with several fields that are the same. But I'm an old software designer so I'll take those frustrations and cherish all the good points of the software. I think its a good solution for my needs in the insurance industry.

Great customer service Great customer service. Earl was very helpful in answering my questions about a free subscription. Easy to use chat feature. Prompt responses. Thank you!
Illyse Harker
Great customer service I messed up, and realized after being billed that I hadn't actually finished cancelling my membership. Customer service (Anna) was very helpful, voiding the payment and cancelling my membership, which is a far better policy than most companies have. Her messages were friendly and the response time was very quick.
