I've added a new feature to the site today: Blogs.  (It replaces "Cards" in the top menu buttons, so if you don't see it, you need to refresh your browser).
Anyone can have a blog.  Just send me a message and I'll set you up.  You'll have your own message board to post in, and you can choose from several different appearances.  See the rest of this post for thumbnails of all your choices.

Here are the current choices for blog appearance.  These are all css styles obtained from http://www.freecsstemplates.org/

Thanks to Hawkeye never settling for the status quo, another template has been added.  It's based on the Foundation template from freecsstemplates.org.
