What is the Age Demographic MFGG is Targetting?

[NowhereMan]

I know when I joined I was like 12-13 years old. I would like to assume that for any internet community like this, it used to be 13-years-old. Is there an age limit at all? Now knowing most of the users are adults themselves now. I would like to assume that the content level of MFGG, itself, is PG-13.
