A user can modify their links as long as they have registered and logged in. All they then have to do is click on 'modify links' from your menu.
They will then see a list of all the links they own in your directory and the can select which ones they want to change. Depending on what settings you have, the user's changes will most likely then be pending validation.
You will then have to 'validate modifcations' and re-build your directory (if it is static) before they will see these changes.
I am not sure I am helping you, as I cannot understand what you are asking
