@Anoni: I know when I was really new and I saw that I was like: "Uhm... what should I do with this? I mean it's still open and a thread is only dead when locked... But red words... Like it's warning me to not post ;-; "
I was so confused xD
@Anoni and Vosur: Maybe it is best to have it removed, or if it serves some purpose to write a different piece of text, although I wouldn't know what.
Sometimes a thread is successfully 'kept alive' when someone would post in a thread that no one has posted in for 21 days (or more) and then it doesn't seem to happen anymore.
@George: Yup, that's indeed what I'm referring to
I think certain boards can have use of a longer period of threads staying unlocked. For example the TV and Video board with sub boards.
