Many forums I am a member of tend to have an area where members can create a thread where other members can ask questions and get answers. These types of forums tend to be quite popular and are a great way to not only allow your members to get to know each other but to also encourage engagement too.
Do you offer an Ask Me Anything area on your forum? Do you find that area does well?
