This has been irritating me a bit for a while, a lot of threads all over the place have Closed in the title, this is wrong, what seems like a smaller number of threads have Full or Not Accepting in the title, this is correct; more often than not anyways.

Closed : A thread that has no activity, is not seeking activity, is no longer kept up, or has reached the end of the story. A thread that is 'Closed' makes me want to move it to the Deadzone, where closed threads go.

Full : Has all the characters it needs, but is still actively running.

Please use these words properly and consistently, it helps us manage stuff and makes things look cleaner as well as more active. We are fairly well acquainted with the threads in the Levels so don't worry about us sending you to the dead zone for changing your title.

(Semi-)Official rule on the matter
CLOSED threads: Threads with CLOSED in the title can be locked and moved at any time.
