I would like to create shortcuts in buddypress. On the main

Hello,
I would like to create shortcuts in buddypress.
On the main menu, I would like users to click lenu items that will lead them directly to the group creation page, lead them any item creation that would normally acess from user profile.
The pb is that in menu, I, don't know how to integrate the variable (username) in the url menu.
In drupal, you get a function ($user=) within the URL that the system will replace with current user name. That will take the current value of the user when the user is connected and then dynamically taking you to the right user page within the logged in user space.

Any advice ?

Best regards,
Hervé
