How to remove "Register" from navbar after....

[Viks]

Hi all,
after signing in to my forums, I still see "Register" on navbar...which kinda serves no purpose.

Wud anyone here know how to remove "Register" from navbar after a member has signed on the baord?

PLUS

I wanna add another navbar just on top (right above no space in between) of the existing one and if I want ONLY the registered users to see it or even guest to see it (like and on/off switch) is there a mod that I can implement for that. I know there is one for adding a navbar but then it shows on the header and it shows to everyone - guest and users alike.

u help will be appreciated,
merci beacoup,

vik
