Are you sure it's incorporated into vB? It looks like an SHTML page. If it's incorporated into vB then it's obviously a hack, since it doesn't exist in vB. Not a hack that's been released here though. You'll need to integrate one of those voting scripts.
The "Add URL" link is part of Links and is not related to the vB sign up. The option to vote for an entry is also incorporated into Links, it's just slightly customized.
