Perhaps they're doing a bit of spring cleaning on the message boards. Recently, one of my massive posts has been archived, not locked, meaning it's completely inaccessible to even view. However, when I looked it up, I found that some of the posts made by Wizard101 employees (such as "New to Message Boards? Here's how you Post" and "Forum Ranks") were also archived.
Considering my post was created in 2013 and still had replies in 2018, I cannot help but to wonder if perhaps they are tweaking their system, which could be causing problems, or if they're trying to do some sort of spring cleaning, and for whatever reason, my five year old post didn't make the cut.
Maybe once they're done they'll start Feedback Friday again. Or maybe they just took a short hiatus in order to prepare for the Decaversary. Who knows.
