When I was on TOS (the other site) there was a bunch of active parenting forums. Even down to the specific month and year your child was born. I've missed that community with other parents here. Does it exist? I will settle for more general if there's activity.
Not a specific one, but join your local city/town/state community! There's lots of cool stuff to learn about your local area, you just have to find it.
Anything that motivates you to post something. Like right now, go to your pictures and find something to post, then find a place for it and post it. Please.
