Thinking about it more, the way to level up skills can be linked to the examinations that Jemel designed. We could link some to ranks as well, so some kind of “Command” trait, which defines whether you can order the launch of a ship, or need to first seek authorisation from someone with the required command level. It would help to define things more clearly. As well as this, we could keep track of things using a spreadsheet, and even link it in with the badge system that we have on the forums.
