Add a small button somewhere in your community, or an e-mail address, where members can submit their own personal news.
When members have a birthday, get a new job, get engaged, have children, achieve a personal accomplishment, participate in a charity challenge they can write and tell you.
You can then mention these events in your news posts. You can do this as a roundup or as a p.s. Mark get engaged today, wish him congratulations.
It enhances the sense of community amongst members and provides simple content you can use. It's very effective for increasing activity and building goodwill between members.
