And... I figured it out! I think! If you click the tab on the top that says "Subscribe" you should be able to subscribe. In Firefox for me, it takes me directly to a link to subscribe via Google, but that's because I told Firefox earlier that I always want to use Google Reader to subscribe. In Internet Explorer, there seem to be options for which feed reader I want to use, so I think I've done this correctly. If anyone has any issues, please email me or comment and I'll try to figure it out.
