fire ashes

Wow, seems like i've started a controversy o_O Anyways, my impression of the whole thing was that as long as i'm in control of things, then it should be okay? I mean.. okay, so i'm letting my friend use a subdomain name. But i know what he's putting on it, because he told me what he wanted to put even before i made the subdomain, the things on his site have, in some way, to do with me anyways, and ultimately i still have the power to go in and delete things. My original question was really just asking for a nicer way to 'exert' my power over him basically shutup

hm..thanks... it's not anything illegal though. the pictures and the media thing were all taken/made by him. yeah. ''

I'm not sure if my question was very clear in the topic, so erm.. basically i wanted to know if you can restrict the amount of space alotted to a subdomain. And if you can, how? I have a friend who i'm hosting and he has this 35meg video plus TONS of pictures...and he's taking up about as much space as i am on my server, and i'm not sure how to tell him to take some things off >< [because, I'M the one paying for it, you know? bleh. i sound stingy now]
