Well my sites internet filter is based out of somewhere, in new york i beleive (Sonic Wall) and anyway, once a week they see what the kids have been doing on the internet, and they blocked anything, and everything that has to do with email, (gmail.com, mail.google.com, hotmail.com, yahoo mail, msn mail....all of it.) also blocked are things like myspace, and tagged, but its funny because IE have windows messenger built into it....so yeah...
