Needs you
Orders from the buy page. When the money shows in the bank account, press Mark paid: the school is switched on for 12 months and gets its receipt. Cancel only an order that has not been paid.
A work address starts straight away. A public-mail address (gmail.com and the like) waits for you to press Start. Cancel stops a trial at once. A trial that was not turned into a paid school is removed 30 days after sign-up, but the address stays on record so each school gets one free trial.
Every PC a teacher signed in on, with the town it was in, the device (system and browser only) and when. No IP addresses are kept. "Sign this PC out" stops that PC at its next online check; a PC with no internet keeps working until it connects or its subscription's stop date. A teacher in two towns may just be at home and at school, so look before you act.
A short pop-up on this computer when something happens, even when the console is closed. It names the school, never a learner.
