This can also be used to move threads posted in the wrong subforum btw. Just write, "Move to Author General, please." or whatever, and the mods can take care of it once they see the report~
I twice flagged ContraOP's "Should dragons have rights" thread during and after discussions of politics and religion, but it wasn't locked. Similar to this, my first thread was really political, and we pinged the moderators frequently (now that I think about it, we shouldn't have done that), but it is still there and has 15 pages.
