I think the main issue has been chat... some teens haven't posted yet.
But if not here then in other threads I have talked about teens that do not have any mental disoder... but are going through growing up or trying to. It's the need for education that amazes me... they won't listen to us, adults, just like they don't listen to their parent. They are argumentative and whiney. And they don't see anything wrong with them and the way they act out.
The teens that do have mental unwellness and have a T and are trying meds or such and going through those issues certainly maintain a different attitude than those that appear to just be juvenile, imo. These teens, imo, may act out but they realize it later and apologize and try to improve. It's a big difference.
When this topic was discuss last year (and/or the year before) the main concern was moderation of a site with teens, and especially if there was a forum for teens. If a forum for teens is created, then a solution would probably include forums for other bulk age groups too. Creating just a forum for teens would make it look, to me, like being a teen is a disorder or symptom in itself.
