First and important - tap the thing below the OP and change it from Most Liked to Newest ( or Oldest if you want ) - most liked is a bit wonky and they are working on it
I would imagine AHQ will remain as it is, at least for now, but that's a good question. I could do with finding out if posts can be pinned too.
I do know posts can be locked, moved, and even hidden, by the CMs ( with the purple Community Admin banner ) or SUs ( with the orange Hero / Hero+ banner ). To be fair from what I recall of the Champion rank that is now Hero on here, with Hero now being Hero+, they may have less permissions but can definitely move posts that are in the wrong place or that are inappropriate.
There is a Report option for posts if you need it, but perhaps don't reply to mis-placed or spam posts and wait for someone who can to come along and deal with it.
There are categories, see the TSTO Panel - General Discussion ( here ), Technical Issues, Tips & Guides and Creative Corner ( showcase )
