Thread

From OLSEncyclopedia

A thread is also sometimes referred to as a topic. Threads are typically started on one or another subject, within the relevant board. For instance, a thread about hockey would be started in the Sports board, whereas a thread about the poster's favorite manga would be started in the Manga board.

The forum's rules state that you should try your very best to post a thread in the most relevant board. While Moderators and Administrators can move threads around so they're in the relevant places, you shouldn't disregard the rule simply because of that ability.

Threads are comprised of posts. When starting a thread, one must compose a post talking about whatever subject they want to bring up. Once that's done, other members can then reply to that thread with their own posts.
