Changes

We made a few small changes:

• You no longer have to be logged in to add a sports site. Frankly, we'd rather lower the barriers to entering data and deal with a little spam.
• There is now a help window that pops up the first time you visit the site (or after you clear your cookies). There is also a link that brings it up on demand.

The idea is just to make things more obvious to new users. We had some feedback that people didn't really know what to do when they got to the site.
