I have the Elvish inscription from the One Ring in two lines in a band around my left arm. It turned out absolutely gorgeous. (Even if nearly everyone who sees it thinks it's Arabic.) I also have a pentacle on my shoulder, a symbol for protection (that really just looks like a fancy 4) on the back of my neck, and Poe's signature on my lower back. I adore tattoos. :)

As For online names, that came up when we got to talking and realized we frequented a lot of the same websites.
