START A DISCUSSION IF YOU HAVE AN OMG STORY YOU WANT TO DISCUSS,
If you have a group, you can develop Multiple discussions in the group. Any of your members can create discussions. I like replying to the question because then you can reply to the replies and not get your reply at the top or bottom, but directly to the person who left it. It really makes a more enjoyable discussion forum. It is better than twitter because people can reply in detail, not just two lines, and it doesn't roll away so fast.
Also you can leave pictures in the discussions and share the discussions and invite more people to your discussions.
The better your discussions, the faster your membership will grow. So Everybody is invited to start a discussion - right here - in the OMG group. go on, tell what you did. LOL, Cause I have the funniest OMG story to tell you. LOL LOL LOL, thinking about it makes me crack up.
