That's pretty pointless, though. There are plenty of other places to host useless junk (try gmail, for one) that aren't going to penalize you very much. Even if you get caught using gdrive with gmail, the most they'll do is kick you off gmail; they're not going to try to press for legal action (as that's far too much of a hassle). If all you want is a storage device, there are far safer ways to do it than hacking a school website.
Of course, if like one member said about useless junk your best bet would be to hack a school website and then upload your useless junk, but of course pray that you don't get caught because you go to jail for that one.
Ah, now I see. Then it's pretty easy, just get the guy to start the paperwork. You pretty much have to; there are no shortcuts to this. But it's not like it'll be that much work...everything will work out in the end. And plus, don't most principals have at least some other people assisting them? It's not like he's the only one handling the paperwork, so if he really, really didn't want to do it, couldn't he push it off onto someone else instead? (Like say, a secretary?) Of course, keep in mind that you don't need an .edu domain to make the high school's website look nice. That depends on your own web design skills and has next to nothing to do with the domain name. Sure, it may sound more 'professional', but 'professional' is more about the look than about the domain.
Its not that I want create a fake site or anything. Im doing this as a favor to my friend, now, the principal of the high school department of a school.
