Active players are always important, but look at the boosted goods of your fellowship as a whole and try to recruit for areas that you are weak in. If you have problems that can be generalized, such as not doing daily rounds, make a general email to all fellowship members to improve. Never single anyone out in these emails. If it's a more specific problem, keep the messages to only the parties involved. And if you can find an advisor to talk ideas over with, then take advantage of that. My archmage truly appreciates my council and the knowledge that I bring to my fellowship.
