I'm so excited to see that this thread is active! I've also recently started attending a UU church and am seeing a lot of the same issues mentioned above - an older congregation. DP and I are among the youngest adult attendees, and most of the others in our age range don't seem to attend regularly. I think UU is a great fit for me so I'm really interested in becoming involved. My family was not religious at all and I'd only ever been to church as a child on Sunday mornings after sleepovers with church-going friends - and I really, really dislike a lot of things about mainstream Christianity.
One thing we're having trouble with is getting involved beyond going to services. We really enjoy the services and it makes me feel so peaceful and centered and connected to the world, but I'm also really looking for a sense of community. Does anyone have any advice on how to get involved as a new, younger attendee? I'm not a member yet, and I know I'll need to join before I can really get involved, but is there anything I can do to start meeting people? My congregation seems pretty friendly, but they're mostly quite a bit older and their social groups seem pretty sealed off.
