Using the www. prefix causes bugs
If I go to www.safebooru.org, the site acts as though I am not logged in when trying to favorite an image, edit tags, etc, but this goes away if I use the address safebooru.org. I keep adding www to the address of websites out of habit, and my browser adds it on if the longer address is in it's history, so it would be nice if www.safebooru.org could redirect to safebooru.org, though I can live with just taking it out of the address when I forget. A reminder on the front page as to whether or not it the site recognizes me as begin logged in would work, too.
