If there is no DJ playing would it be ok for DJ's with the proper registration to fill dead air anytime they feel like it?
I believe you are already allowed to do this - that is, to fill a particular timeslot on a one-off basis (obviously, within reason). For the purposes of etiquette if you're gonna fill in you may want to tell people, but as far as I know you can.
The other suggestion is a radio notifier on the main page or forum page or both.
Well, I know Ante has a banner in his sig that shows:
- The status of the server (online or offline)
- The number of people listening in
- The current song playing.
It automatically regenerates depending on the server status, and I don't know how to arrange it to get the DJ/song title, but it's definitely something to think about.
