unwanted margin for custom list

if you take a look at my page, you’ll I’m trying to make a sort of alphabet calander with an inline list. but I dont know why there is a margin on the left. I want it to line up with the rest of the items in the sidebar. also, I havent’ figured out yet how to space the letters so they fill up the width of the side bar and look more like a calander. maybe someone can help me out, or point me in the right direction. my main problem is the margin. I made my own css div called alphamenu. my site: metalherig
