I tend to edit posts a lot, as I only see errors or typos after a full readthrough after a thread or reply is posted. One thing I’ve noticed is that after editing, my post goes to the top of the subforum as if a new reply was made.
While well-intentioned, to me it sounds like this system is ripe for abuse; a Let’s Player frustrated about a lack of traffic to their thread can make one simple change to the OP, bumping it to the top, without actually adding new content. In effect, it could cause necroing without the need to even make a reply.
Maybe I’m just being cynical, and it’s the first thing that came to mind because I’ve worked in QA before, but I thought I’d bring it up as something to possibly fix or remedy.
