Membership Plug - Default Welcome Page

I went through the instructions painfully again trying to get this module to work at just a basic level.

What I can't determine is how to change the page that a registered member lands on when they login.

Right now it defaults to a custom Sign In page that is the "Registeration Page" as described in the plugin install directions.

I need a custom "Welcome Page" that Registered Members are shown once they are logged in.

How do I do that?
