Answer Me This: Wordpress

I know most of you use Blogger, but does anyone know how to Log In to Wordpress?? I used to have a blog there when I first started but shortly after switched over to Blogger.  When I leave comments on certain people's blogs, it has a really old profile pic (Eli was 4 months old or something) and I'm wondering if that's linked to my Wordpress account and would like to change it or something but can't find where to log in anymore.  Anyone know??
