Our computers restrict Facebook, as long as we cared. Sense we do almost nothing during tech lab but get on and play games, everythings open, Bubblebox, Gmail, anything really, even the forums, Youtube too, they encourage us to get on that too, we have our own Gmails for school so we can get on that, anything google, games, he gives us games to play.
Hes a teacher that uploads the assignments on Edmodo.com, which everyone in tech lab has an account on so we can read what we need to do there instead of him telling us, we get on there, read what to do, click the link he'll probably want some game to play. He wanted us to play like, Scary Game 3 or something, funnystuff.
Hes pretty cool, Im his like, favorite sense I talk about computers alot too.
TL:DR = Lazyyou
