Locking a question typically prevents regular users from answering, editing, commenting on, or voting on it. Only site moderators may lock or unlock posts, or perform restricted actions on locked posts. If a question is locked, any existing answers on it are not automatically locked/affected by these restrictions. (For issues related to locked answers, use the [locked-answers] tag instead.)
