I have added two new features and fixed some bugs. First off, you can set yourself invisible (i.e., so other users on the forums don't see you on the online list) by going to your profile and checking the "Invisible" box.

The second feature is that you can put your location in your profile, and this will show up on your public profile page.

Thirdly, I fixed a bug with the "New Posts" button. It was breaking and not showing some posts as new like it should have been. It should be working now though.
