i love addictinggames..i play on it all the time at my other job haha.. but do you want to know something funny? they've blocked that too
it's like they've blocked anything and everything that takes more bandwith then simple internet browsing. there is a way around i just found though.. they've got some wireless stations up here that for some reason aren't controlled by the webfilter.. but they're hella slow.. like 0.6mb/min download speed
