To test a bunch of features all at once, I'm going to pander to the cheapest trick I can think of: A cute animal contest.
The rules: 1). You have to post a photo (or video) of an animal to your blog; 2). you should post it by answering the call in the Open Call box on the homepage, OR, make sure that your post has an "opencall" supertag selected at the top of your post (it's the right drop-down menu under "Tags.").
At the end of Friday, the blogger whose post has the highest rating wins a very special prize. So post -- and rate each other's posts, too.
I'll kick it off with an angry photo of my cat, Lucas.
