The site is very easy to navigate. I'm a novice when it comes to anything to do with forms, etc. Your site is so easy because it's intuitive. It just makes sense about what to do next, no hunting around trying to figure what the site builders were thinking. Easy peasy.

AWESOME SOFTWARE
Great software, the only challenge I had was the sign in process. I have had a few accounts as I had challenges signing in and ended up making additional accounts. This could be user error but I am sure others have had this issue also.
