First of all, this site has been a great help so far for the new look of my desktop (I thought it was rather boring and could use some work)
I was wondering about something though :

I've seen ways to add a button to log out and reboot the computer, which both work fine, but is there a way to add a shortcut to for example objectdock for the Windows XP Fast User Switching option? (Clicking on the button won't log you off but keeps you logged on and shows the graphical logon screen of windows XP, so more then one user can be logged on at once)
I haven't been able to find a way to do this (I did find a few nice icons for it but that's only half the job
Any help would be appreciated.
