I'm not a teen, i'm just going by my years on the site, what i've seen and heard on the topic.
But i'd have no idea what to do. Even the Teen forums are not heavily used here.
Really i think the teens follow the busiest room and some probably prefer the older people in the Lounge as well. Not enough younger teens to keep things active and the older teens largely want to get away from teen things and into adult things, hence them being in the Lounge.
