Happy Birthday Kimi.
As per your question, I think I speak for all the voices inside my head when I say that there is a total absence of a concept that denotes age on the internet. (Unless we're talking about pornsites, where there is a strict classification of which belongs to kiddie porn and which passes as an MILF)
So, Like I said above, Happy Birthday and unless you're old enough for your dessicated fingers to crumble into dust or I don't know, burst into flames while typing on the keyboard - you shouldn't leave the board.
