As an archmage myself, I understand what you are saying, you want the fellowship to be as active as it can be. First it is hard to see if a member is taking trades, unless they are taking yours or are on the chat and say that they have taken a posted trade. Your member might be taking trades that you are not seeing. If they have only their boosted factories they most likely are taking some trades, if not you might want to try and persuade them to do so by explaining about how much more goods they can make and how much space they could save, and how it would help the rest of the fellowship, if you have a good balance of boosted goods,( if you don't have a good balance of boosted goods, members trades could sit for a long time and that isn't good), but be gentle, no one wants to feel like they are being told how to run their city. Also are you at 25/25 members? If not I would say that an active player that visits is good enough, until you get it to full. I also agree with Soggy, that this could be something to ask the fellowship as a whole so that every member feels like they have a say in how the fellowship is going to progress, this also takes some of the weight off your shoulders as its what the fellowship as a whole wants. Good luck with your Fellowship, your off to a good start, as asking for advice shows you are open to suggestions and that's the best way to run a fellowship!
