Developing this comment from Oktar.

“As for a community, he'll help in a sense of helping to keep it bounded, nicely so as not to have conflict between the community and the natural area. For Thistletop in general, Oktar likes to have a place for people to go, who would otherwise be oppressed and shunned. He'll emphasize that freedom he also emphasizes responsibilities, chores and rules in this community. He'll expect even the youth of the attached community to have some organized service to the whole. Like scouts or chore teams.”

However, I think we could give people a choice of how they serve the community. Some Obvious ones …

• Militia - once a month, the Militia is mustered for drills and training under one of the more experienced melee fighters. It should probably be Sir Robyn, although Dru or one of the senior guards could share the responsibility. We might want to encourage this by giving away padded armour to those who attend regularly and can show proficiency in a weapon. Based on The Fyrd, with minor modifications. I would probably base it around free weapons (Club, Quartertaff, Sling) for commoners, with Spear and Darts for experts. If nothing else, it trains/retrains the Commoners' single weapon skill to something useful. However, Artifex might also allow a second weapon, or even a point of Prof:soldier as a Commoner Trait.
• Scouts - Let's steal from Baden-Powell's original setup :) A youth organization (in this case, male and female) that deals with basic survival skills and trains the members as messengers and runners. That could meet weekly, as do most RL Youth Groups. Later we could add sailing and other skills, tie that in with later militia service, and we might give some of the children a chance to develop into Experts, rather than commoners.
• Religious/Philosophical - My neighbour spends a lot of her time cleaning and arranging the flowers in a local church. In Thistletop we will (eventually) have a temple to Sarenrae and a shrine to Desna, which could provide a similar commitment for residents. We are also promoting 'The Green Way' as a philosophy, so planting and regular maintenance of community flower or vegetable patches might work for that.
• Work Groups - local community infrastructure always needs maintaining - paths need some clearance, bramble hedges need trimming, and I am sure we can think of other community infrastructure later.

Note: Some of the earlier suggestions are based on how I run games, and Artifex might have different ideas about NPCs :)
