I doubt if the administrators can add a function like this because this forum is a "canned" solution, if it is not in vBulletin's package then it can not be done.

More options...
You would probably like google docs. Anything you put there is accessible from anywhere.. A document with links could be created.

Get a free web site from Lester and have a "Links" page.

Or..
In you user profile post a message to yourself with forum links.
See my profile for an example.
