One of the things that was also suggested was that when someone does send a message to everyone, that it is also automaticly posted in the fellowships board - that way if someone does "opt out", they will not miss messages in case there is something important.

And option to opt out of individual fellowship messages is a good idea..... if it does not take too much extra work. (I'm up to over 20 messages in the past week which I don't consider important - that is messages which could have easly just have been posted on the fellowship board, and not put in everyone's message box.)
