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 )
You can also add Tags to the OP in a thread. On here that's Feedback, Finding Friends or Ideas. These help to filter things if you then use the Tags option to find posts. Different categories will have their own relevant tags too, but if you think there's any that should be added create a post and suggest them and one of us SUs or CMs can pass those along for review. Do make it clear what section they're meant to go in though and remember the Tags are meant to be general, so don't ask for tags in the showcase for every event or building !!
Right now there's only 2 very old friend requests tagged Finding Friends so it won't help much yet.
I've asked about a pinned thread for Friend Requests, or for them to go in their own category, but this is an ongoing project and they're working on the sections for a load more games yet as well as bug-hunting and fine tuning everything, so that may take a little while if it was to happen
