i'm running dnn 4.02 and am wondering how i would/could go about doing the following...

i want the root page of my domain (http://<mydomain.com>) to be a simple landing page that provides a login control and a very brief welcome message.  upon a valid login, i'd like the user to then be presented a basic 'welcome' page that now displays some valid content and a logo/banner at the top of the page. 

what i've done as a first step is make just one page that is the main page, but have defined different modules that have access levels set so unauthenticated users see one thing (the login module & brief welcome message text box) but registered users see another (login module hidden, valid content box).  this has provided largely what i want- one page that is the root page that displays the appropriate content to the appropriate type of user.  the problem here though is the logo.  i'd like the logo to only be viewable by registered users, but can't see a way to do this.

one idea i had was to create a slightly modified skin version that didn't have the logo elements in it and put the unauthenticated user-visible modules on that page, then a separate page that had the logo elements and put the registered user-visible modules on that page.  the problem with this though is that once the user logged in i'd want them to be automatically transferred to this second page, but can't figure out a way to do that. 

can anyone advise me on a way to do this?  might the 'page management' settings under admin->site settings->advanced settings->page management be of help here?  i'm really not sure what 'splash page', 'home page', 'login page', and 'user page' do. 

thanks in advance for any advice!
