I would like to add a menue entry (called User Account) to the menue (or near to the Logout Field) if a user is logged in.

(I wanna make this entry to a central point where the user can find further links and options)

This menue entry should only be shown, when the user is logged in.

My questions are:

1.) How could I reach the page, which is shown after a successful login. )It's the page: login_success.html,
In this page I added the other links and created a news section)

2.) How could I show an own html page, which I created. ( The login_success.html already existed and is used but how do i start an own written page.)

3.) How could I check if the user is already locked in. <%if .....
