How do I unblock Facebook at school

You don't... ever... ever!

School = study! See, simple maths! Lol!

We here at AMHD cannot help you get around any sort of administrative restrictions imposed on a School, Work, or any other network not owned and operated by yourself. These restrictions can include (but are not limited to): Website Blocking policies, Software Installation policies, Email retention policies, Software Configuration policies, Network/Internet usage policies, Network Configuration policies, Forum or Chat Room Bans, Game Server Bans, or any other actions that are deemed "unauthorized" by the owners/administrators of the network in question. Any actions by members of AMHD that would be offered to help in this manner would directly violate the site's TOS

Question Closed !!!

There are a few threads that discuss this. The bottomline is that a school or company has the right to control what their computers are used for. Students or employees do NOT have the right to try and get around that control. Attempts to do so can result in suspension or termination. Therefore, it would unethical for you to try and unethical for us to help you do so.
