How to move Ubuntu 12.04 launcher to the right?

view story

http://askubuntu.com – I've just upgraded from Ubuntu 10.04 LTS to 12.04, and the launcher is on the left side of my monitor. This is great, except I'm using a dual screen setup and my main monitor is the one of the right, so when I select my main monitor as the one where launcher resides in, it's residing in the middle of my extended desktop, causing problems when I try to mouse between screens. How do I place the launcher on the right side? Thanks (HowTos)
