Flag Stuff
I can't stress this one enough. While the site is relatively small, we can watch over most of the content that goes on here ourselves. But, doing that is a lot of work and we do have other lives, believe it or not :) . This is what flagging was designed for. As you go around the site, if there's something that looks bad, strange, or worthy of some form of action, flag it. Our flag queue has seen 2 flags in the last 5 days (I think) - it's not like we've got masses there.
Talk to us
Come and talk to us! We've got The Rec Center, our chatroom, and we've been seeing some new faces recently - which is great! Come chat to us, just generally, or about stuff you've found on the site. Got an idea but not sure if it's worth it? Come and get some quick feedback from someone in chat. Occasionally, one or other of us drops something into chat that we're not sure about, and asks for feedback on it.
Meta is Not Murder
(reference)
The more people we have on Meta, the better (pun rhyme intended). Meta is where we live, mostly, and it's important that plenty of feedback and discussions about the site are had there. Disagree with an action we've taken? Meta. Want to see us take an action, and nothing's been done? Flag, then Meta. Want to solicit feedback on something about the site? You get the point.
Vote
And by that, I mean all types of voting. Normal up/down voting shows us what the community here think of questions, which allows us to help future posters with advice for their questions. Close voting helps us to recognise what the community wants in scope, and is also very helpful in borderline cases where a hammering isn't appropriate, but the question may need closing anyway.
