I have been testing this module for a few months now and have been in contact with Muhammad Ilyas many times asking questions and suggesting improvements.
This is a VERY good module for managing workflow on web forms. The module allows for the custom creation of forms and has a system to define document statuses and actions that are to be taken when certain conditions are met. There is the ability to setup automatic actions and notifications to different groups in the workflow. In the end, I was able to quickly setup a vacation request form that flows from the requester, to their department supervisor, and then to our payroll processors.
Muhammad has been very responsive with questions, bug reports, and enhancements that I asked for, even before I purchased the module. The turnaround time for support has been excellent.
I would suggest this module to anyone that is considering workflow processes for forms on their website.
