kinda just fell into my head because I am 11
In general, yes the site is fine. We moderate the Q&A pretty well. But we can't protect you from anyone swearing or talking about mature subjects on the chat room, so you may want to avoid the chat room.
Actually, I will soon be adding some Terms & Conditions to the site that say anyone under 13 (actually, anyone in general) uses the site at their own risk. There is a legal thing that means you must have specific measures in place if users are under 13 and I don't have the time, resources or effort to do that.
This can be a good site for anyone as long as you follow the rules and have a decent amount of respect for authority.
Although some of our members have been spewing out profanity in the chat room ( Most of which are about 10 years old... )
This site has a pretty fair amount of morals, and as I said before, It can be a good site for anyone.
