Wulfir noticed you have another one going Autumn 73, I was going to download it & tag along as having great fun in this one
Suddenly thought I assume its possible once the player/you have had enough to actually release as a User campaign for general release. Could even ask the players for a little feedback make the odd change if like though if mine is anything to go by standard is high.
Campaign designers in general this is a very good way of playtesting if release to a small group of volunteers.
