Hi Bill,
OK, in that case give our ACL control lessons a try within our "Users" section of our Intermediate class:
www.ostraining.com/courses/class/joomla-25/j25-intermediate/
-Understanding Joomla Users
-Joomla Access Control
-Joomla User Groups
-Setting Your Own ACL - Part 1
-Setting Your Own ACL - Part 2
-Adding an Editor to Our Site
You can redirect the users to any page that you'd like by going to your Login menu item within menu manager and configuring the "Login Redirect" option on the right side.
Hope this helps! Let us know if you have any questions after going through the tutorials.
Kind regards,
Nick
