What on earth is a Fitter message?
Think Twitter! A Fitter message is a short (200 characters) text like message which can be uploaded to the satellite (via a moderator), and which can be transmitted several times every 5 minutes or so. It will continue to be retransmitted until such time as it is replaced by a new Fitter Message.
So such a message could be something like:
Greeting to xyz school, which will be hosting GB4FUN on xyz Date. We hope you receive this msg OK!
There will be space for a total of nine such Fitter Messages.
