Change Login/Logout in blocktopmenu

[Zet4]

Hi,

 

I have a menu with a link "Log in" and always is static.

I need change Login/logout when user is logged in or logged out but in this module i can't use typical {if $logged...} because the chunk of code that check this is for any link that you put in menu, and I just need change this link.

 

I though use javascript but i can't check from javascript if a user is logged in or not and after change html title and "a" tag.

 

What do you suggest?

 

Thanks.
