I noticed some threads have a red dot or a padlock next to them. Whats that?
The red dot is actually a thumb tack, indicating that the thread has been “stickied”. This means that our moderator, WhiteKnightonTV, has specially marked it so that it will appear at the top of the page whenever anyone enters the forum. Stickies are reserved for “official” threads, such as threads discussing episodes and the off-topic thread, so that no-one will miss them and post messages that belong there someplace else. The padlock symbol means that WhiteKnightonTV has locked the thread. Once a thread has been locked, no-one is able to post in it. This is done with threads that do not require comment, such as the FAQ and forum rules threads; and also with threads that have gotten out-of-hand, such as threads that have denigrated into flame wars. Finally, duplicate threads are locked so that people will move their conversation into the appropriate thread.
