I don't think kids should host for many reasons. Example below;
11:00am - My site's been hacked and someone is sucking my bandwidth.
11:05am - Try's to contact host :::: NO REPLY ::::
01:00pm - No reply, by this time, I have no site, all files have been deleted by the hackers & my bandwidth has been sucked
03:00pm - Host comes back from a nice day at school
See If my host was here at the time he could of stopped this from happing, but no because he is only a kid he's in school learning his maths & english.
Also kids change their minds quickley, this week you could like hosting & next week something like Fireworks...
So then you stop hosting and your customers are stuck
