|
|
|
+ * - locks a topic, toggles between locked/unlocked/admin locked.
|
|
|
+ * - only admins can unlock topics locked by other admins.
|
|
|
+ * - requires the lock_own or lock_any permission.
|
|
|
+ * - logs the action to the moderator log.
|
|
|
+ * - returns to the topic after it is done.
|
|
|
+ * - it is accessed via ?action=lock.
