CB invites (and others)

Hi
I have a cb content with substitutings in main menu: for cb invite.
When I am registered it works fine and leads me to my invitation tab.

When somebody is not registered it says: Please log in or register to view or modify your profile.

Is there a possibility to input a link to the login/register page? (because I am using the menu to login)

Sorry, don't understand what you're referring to. CB Invite doesn't have an overview page anymore and is purely managed from your profile now so you don't need a link going to its frontend (it'll just redirect to profile view).

Sorry, was not clear enough.
I want that not registered persons can see, that it's possible to invite friends.
So I use an cb incubator menu in the main menu! This menu is publicly visible!
When an unregistered person is clicking on this menu item, comes "not authorized. Please login or register".
Then the person has to look for login and then come back. Mainwhile he forgot what he wanted. (Me, I am like that )
It would be nice, when there would be a link to login directly after "Please login or register". Is this doable? And how?

There is no menu link to CB Invites. CB Invites can not be used publicly. Invites are managed completely from your own profile.

It would be nice, when there would be a link to login directly after "Please login or register". Is this doable? And how?

No, that's an error kicked by CB. You'd need to edit CB to change it or add a redirect.
