A couple of ideas from me:
To get things going, an introduction thread, so that anyone whose currently around has a chance to start a dialog with each other, or an "ice breaker" so to speak!
Also, a weekly "Let's chat / How is your week going / Venting" thread could serve as something that I can imagine everyone here would appreciate. I tend to notice that communities are often ran on news and shared experiences, often times I find that when I enter a community I'm not 100% sure what is allowed and what isn't allowed so I don't want my first impression to be posting something that isn't acceptable. While I suspect that there would be no issue with a thread like this in this community, for me (and I imagine a ton of other people) the hardest step is getting your foot in the door.
