Was just wondering how someone managed to post yesterday on a forum thread that was closed in January.
Is this a forum bug or has someone found a way to over ride forum settings. Either way this probably needs looking into.
The thread in question is located in Feedback Corner.

Don't think it's a bug. I saw the post and checked and the thread appears to not be locked as claimed. Maybe it was unlocked so someone could edit a past comment and was never re-locked.
