Each bulletin board covers a topic.
Users can read messages, post new messages and reply to existing messages.
Replies can be placed back on the bulletin board, or emailed directly to the author of the message. These provide a forum for Christians to share what Jesus means to them and in general debate what Christianity is all about. These groups also provide contact with non-beleivers and hence the opportunity for evangelism on the Internet. Often this can lead to developing a relationship and the chance to share Jesus with that person through email. We can still use these groups for evangelistic purposes though.
