Yes, at the bottom of the page, I saw it, I always thought it was at the top of the page, and then I was confused. Haha. . thank you!
If you are the one who locked it then it can still be unlocked when you want to. This is used mostly on a thread about giveaway or something like that where the op must locked it temporarily then unlocked it but if the mod is the one who locked it then it cannot be unlocked by you unless the mod unlocked it.
