But please keep in mind that 100x100 pixels is not a lot of room to work with. Your text of choice can't be paragraphs upon paragraphs. As much as you can shorten it down, the nicer it will probably look. If you want to see what kind of text icons I do, here, here and here are all my examples. The icon will probably be done in Century Gothic unless you specifically ask for another font.
Also, please pimp! The more requesters the merrier. :D
ETA: Please state if your icon is shareable when you comment.
