There s a firewall blocking my yahoo mess ager i cant get past it help?

I am uming that this is at work or school. While there are ways to get around a firewall using proxy sites, doing so is considered to be a form of "hacking" and is a misdemeanor in most states and a felony in the others. It can also be grounds for suspending you or firing you. There is nothing on Messenger than can not wait until you get home. Is it really worth risking a criminal record for?
