Potentially, if people are not taking part on a regular basis. The experience gained from each session will be roughly the same from session to session, I will try to work that in. But people who miss out on the odd one shouldn't be more than a level or two behind the others. The fairest way to do experience is to grant it per session you have taken part in.

As a general note if there are people who end up missing most of the sessions and making it to the odd one or two out of ten, then I will be using my unfortunate duty as GM to ask if they want to continue or if they want to step down.

As a note if you do like progress and growth then you will want to know that I intend people to be levelling every two or three sessions.
