Our 9.0 version contains a whole new family of skins you can choose from to jazz up your IM window.
When you choose a new skin it changes the design of the headers of your contact list as well as your IM conversation window (and adds some accents in other areas).
To change your skin in Yahoo! Messenger 9.0, click the gold dot up near the top of the contact list window. It’s located near the minimize / mazimize / close buttons. Once the skin menu appears, hover your mouse on a skin to view it, then click to select it.
There are currently seven skins to choose from in Yahoo! Messenger 9.0 including graffiti, green fantasia, icy blue and violet flame.
