I was just thinking that it would be really cool for this forum to have a chat section! I'm part of a fish forum that has this function and there is a large group of us that spends a lot of time on there every night talking. We have an absolute blast! People can come and ask fish questions and get live responses OR we can just chat about every day things. It's fantastic!
That particular forum also has a "Thanks" button at the bottom of each post that's made. That way, if someone has said something kind, particularly helpful or made a comment that is useful to a lot of people, people can click the "Thanks" button to show appreciation. (If you click the button, at the bottom of the persons post it will say something like, "Zero's Mom says Thanks."
Just two suggestions that are a part of another forum that I know everyone has really enjoyed using.
