Everything seems to be fine here now. I'm at one of the primary schools at the moment, but it's in the same 'cloud' as the secondary school I'm based at, and I'm using the same proxy so I guess either someone else in Sandwell has requested for it to be unblocked, or someone that works for them didn’t like being blocked.
I just did some testing. It seems that "edugeek.net" is infact blocked; however, "www.edugeek.net" is not blocked. I always knew netsweeper was bad and let the kids get around it easily... But that's just stupid!
