I assume everyone's noticed that the front page layout has changed. On the right side of the page, you'll see a number of boxes, which contain links to recent and popular art. In particular, take note of the "Favorites" box. Registered users can add art to their favorites by clicking the "Add to Favorites" button on the bottom of an art page.
I've also done some clean-up in the forum area to make it a bit clearer and easier to use. As always, please let me know via the forum if you have any comments, criticisms, or ideas.
