The title of each inlined message is a link to a page with only that message on it, so you can go there to reply to it or do other things with it. Navigation You can use one of several navigation buttons to simplify reading of neighboring messages. These controls are only available when reading messages within a forum, not at the level of the base article. Next Message Go to the next message which is replying to the same thing as this message, skipping over any replies to this message. If there is no next message, go to the next message one level up.
Previous Message Go to the previous message which is replying to the same thing.
If there is no previous message, just go up to the immediate parent. If there is no reply, go to the next message at the same or higher level. So you can use this button to read every message in succession, but keep in mind that this is not necessarily the same order that the messages were written in. How to Add a Message Use the button to add messages, both top-level messages in a forum and replies to other messages. Text in the Title field should say something distinctive and succinct about your message.
