When I go to the University of Alabama campus my wifi kicks in on their free public wifi access. But I constantly receive this annoying message regarding the expiration of their certficate and if I want to view it. Any way to disable this message? Only happens on their wifi connection; att and others is fine.

I don't think so, this message should be going out to all the users who connect to that particular Wifi. The only way would be to disable it from their server..
guess your'e stuck with it unless you turn your Wifi off..
