I still wish my job would NOT block GC. It's the "chat" part that does not make it past the filter. Even the customer access computers block it. I think I was only able to access it one day.
Proxy servers don't work?
I'm able to access MySpace at work via proxy server. Not all graphics come out, but usually I just check it to read messages and comments.
My work blocks proxy servers too and if you find one that they didn't filter out, and you are caught using it to bypass Websense, you can be fired. Happened to a really nice guy in our department who was using it to get to MySpace.
I'm lucky - we have no firewalls blocking sites where I work. Part of my job actually includes perusing other Web sites (I'm the News Editor for a national organization).
During the day, I open three Internet windows: my work's home page, Google and Yahoo. In the Google window, I open two tabs: Greekchat and eBay.
