Saving UserName from a Login Contorl

Question

I have recently had to add a login page to a web app.  I used the following MSDN "tutorial" to create login and welcome pages.

Walkthrough: Creating a Web Site with Membership and User Login

I am now attempting to save the user name and pass it to the application so I can insert the user name into a table when appropriate.  I cannot capture the user name.  Suggestions please and thank you.
