If someone is mature and follows rules like they agreed to do when they downloaded FeralHeart, then no, age doesn't matter. I know a nine year-old on here who acts older than I do sometimes, and I'm sixteen. I think as long as you're capable of being a mature, sensible person, I don't care how old you are. Sure there are laws and such, and those should be taken into consideration, but if they weren't there, age is but a number.
