From someone who spends way to much time on the net and on various boards, nothing would kill one faster than to try and charge for it. As soon as you instate a fee on it someone else will start one up that's free to replace it and everyone flocks to it or to one that's already free, or one that's good and very well established i.e. BNO. Who has a thriving board in existence that charges for it? I'm not saying there isn't one, but it would certainly be a different niche from the small quirky hobby we have. There is no question that there is a tremendous amount of value here, but it is what it is, a BBS. Those are my thoughts.
