I had no idea I could lock it myself. Wheres that option located at on the thread?
It's under thread tools in the upper right, deselect "open". You may also see a checkbox that does the same thing next to the thread title in the forum list, though you may have to enable moderation first (that's new).
But in answering your question I just noticed something new - it looks like you can only lock / unlock threads in the exchange section; it used to be you could lock your threads in discussions, too.
