yeah, the .org sites are always like educational or something good. they usually dont expect .org's to be anything but them. so if u find a .org gaming site, good job.
Sites that have edu at the end are always opened to us because what they did to our systems is when ever you type in a web addy if it dosen't have edu in it, it adds it at the end and thats what blocks most of the sites.
But where there's a will there's a way.
