Don't understand a word of it, but I do know that I can take my laptop to the Public Library when I visit the USA, and see everything except my Outlook Express, so I can't download from my NZ ISP webmail to the laptop to read Offline when I get back to the apartment, I have to read and reply on the Webmail in the hour per day I'm allowed to use the service.
I complained and was told that it was deliberate, 3rd party e-mail accounts - they said - were deliberately blocked to protect from Spammers and Porn.
Makes sense I guess, and would have tried to get around it, but have discovered that if I sit outside Starbucks around the corner, I not only don't have to buy their coffee, their free WiFi connection allows me to use Outlook Express without any trouble.
