One type of a forum is an online discussion site on the Internet. Users can type messages for others to see, and reply to other user's messages. Messages (or "posts") are organised by topic (or "thread"), with each poster either replying to an existing topic or creating a new topic for a new conversation.
There are usually three different types of rankings on a forum:
- Member: which nearly everyone is, they can read and create posts.
- Moderator: someone whose job is to keep order on the forum. They can delete posts and warn or ban members who break the forum rules.
- Administrator, or admin: The highest rank, who can change settings on the forum and change user permissions.
People participating in a forum may make friends with each other and may form groups with the same ideas.
