We converted to RealPage Onesite in 2013 and use most of their platforms. Overall it is a great software, some minor frustrations with the platforms don't always work as seamlessly together as they like you to think but we continue to improve our operations and continue to add new platforms as needed.
We were unable to use the bluemoon forms due to the constraint of signature lines allowed on their forms - we completed our own form packets and used doc management to create our forms with custom and generic merge fields, the possibilities are endless and we continue to streamline and add forms to the sites library of forms.
