I think it would be awesome to have the ability to lock your own thread. This option would appear in "Thread options" where it currently allows you to change the title. I created this because it is more convenient then asking a staff member to lock your thread for you, and wasting their time. As well as making it more convenient for you. EDIT ONE: This would only be allowed after a certain number of people reply to the thread. (2-3) EDIT TWO: (Didn't see @Amcra 's response) There would also be a pop-up on your screen asking you weather or not you want to lock your thread, explaining that you cannot unlock your thread, etc.
