I'm very interested in using DNN for a customer portal and I'm currently searching for any existing modules that will fit my requirements.   If anyone knows of something that can fit my needs below any help is greatly appreciated.

I need a module that allows me to create pages that allow customers to change their user settings for my service.  The user settings would reside in a database and for all intensive purposes we can assume it's just another table added to the DNN database.  Each user would only see his account information based on his login ID.  So basically I'd like a module that gives me the ability to create pages with dropdowns of pre-defined variables and stores the users choices/changes to a table in the database. 

Thanks in advance!
