You may use a text code or a image code, whatever you prefer. For the text code, put something similar to Forget Me Not Fanlisting.
All the image codes are below. I will be getting a variety of sizes but, for the moment there these are the ones I have made. You are more than welcome to donate codes or make your own. Donators will be credit of course. If you make your own, please think of putting it here for others to use, since my button making skills are not up to par.
