Thanks for your response. I am aware of HIPAA requirements. Security and best practices to protect against data breach are always an issue.
But, there are numerous plugins that allow a backend user specific private area for messaging, etc. which is perfectly acceptable.
I was looking for something for user specific (login) portal tracking for individuals who would be able to login, access a simple data tracking sheet, and have that sheet translate to graphics that would allow them to visually monitor their own progress.
