I recently finished setting up an online radio station for a client using WordPress. It offers streaming audio in multiple formats, a members only podcast on-demand section and a members only webcam. It also uses a featured content slideshow on the home page to announce new features and programming info, a chat room, and a discussion forum.
I've put in a guest user so you can look at the members section (it will only be there for today) username guest, password 12345.
It's one of my first WordPress sites I've done, so I'd appreciate feedback, suggestions, and comments. Thanks!
