ok myartonline.info use 2 work at my school but they blocked it now. you should try that. maybe it will work im not sure. just type in the website you want to go to at that site.
Im in computer apps class right now, i dont understand why they dont have a system where they can turn the blocking system on and off at certain times. so in the morning b4 school we can play all the games we want, then they block them.
