Of course, there's nothing to stop you and some like-minded FoLCs under 16 starting your own channel on irc, Anna, to hang out in, until you can join the others, too.
There used to be such a channel a long time back, but I don't think it still exists.
Setting up your own channel couldn't be simpler though - just think of a name and open it up, then announce it here and invite others to join you.
