Ah yes. WebSense, how I hate thee.
WebSense is blocking many sites at work, inclusing this website because it falls in the category: "Message boards and forums."
Working in an IT department we convinced our superiors we needed access to message boards and forums to research certain problems. The rest is history
(this is definitely not a lie as we really do look for solutions on forums).
WebSense is draconian... there's some workarounds though. Find a good anonymous webproxy (of course there's a constant war between WebSense and the proxies, so it's hard to find one that isn't blocked in the category "proxies") or plug in an internet phone and use it to browse the web. These solutions could get you in trouble of course
I am kinda crusading against WebSense as the moment, as I work not only in the IT department, but specifically the internet department. It's sometimes difficult to do my job with all the sites that get blocked. For a recent project I had to visit some gambling sites for example. Joyous times where had by all, before I got access to those sites through the company network
