how to write a single logout link for all the Role Groups?

Hellow,
I have created a role based menu for my asp.net 3.5(C#) by configuring Asp.Net Membership module for site.
My role based menu is a nested HTML unordered list. And each list item has a list of links. And at the end a list item has SignOut link.
I have created 5 role groups for my website and put this list(i.e. menu) inside the contentTemplate of each and every role group.
I have display the SignOut link by using LoginStatus but I dun want to put the Login Status in each and every Roles Group.
Can anybody tell me how to create a generic view which will display the Signout link when any user is logged-in. But I dun want to show the SignIn link when the user is not logged-in.

Regards,
Dazy.
