Ah, ok. I bookmarked the page in case anything happens.
After thinking for a bit, I remembered another friend who I think got on the school computers once, but he never really gets on his nation at all, anyway, and he's really new. Blocked both so I don't mess with them. I'll let both know when I get to school, and any others who might try to start a nation on the school computers. That'd be disastrous. D:
I don't think I have anything left to ask... So thank you all very much for your help. Very quick responses, too. <3
