Jumptown has a family feel to it, the jumpers look out for each other which is nice. I've heard second hand some people feel it's "clique-y". I would disagree, but can see how the family feel could give that impression. One of the more experienced ladies there has spent a lot of time and effort developing a strong SiS program. Ask manifest if someone could talk with you about SiS and what they're doing with it. They have a lot of skills camps for the various disciplines, depending on what interests you. The post sunset actives are a bit tame compared to some DZs: Small bonfire, beers, jump talk.
