Welcome to the Dark Side.
WARNING: These icons are in their original sizes. They look huge, and take up a lot of space on these pages, but fit in your MSN perfectly. I'll prove it to you - check the bottom of the page. It would be pointless and take forever to resize them.
Ok, welcome to the most basic icons on the site. Have a search around, pick up some icons, and voila! You're done. The icons below are basically just random stuff that sounded cool, so it should be. Have a browse.
P.S The banner above is a link to the next page.
