how do i disable the display livediscussion in Navigation

I don't want live discussion link show up in navigation, how to do that?

Since I have live discussion for the whole site on a node and each user can go to their blog aggregated blog/9 to see their recently commented threads.

i can disable lived iscussion in menu when I am admin, but there is no way to disable it across all sites, therefore, logged in user always has live discussion in their navigation, linking to http://example.org/live_discussions/9 (is it's user/9)

Live Discussion is a must have module. Thanks for the effort.
