MailMyWeb may be an option for those of us whom face issues with websites being blocked (for example a few weeks ago HelpKidzLearn was blocked at my school because it is listed as "games", luckily this was resolved easily with an e-mail to IT, but in other school I have worked in once a site was blocked there was no way to get IT to unblock it).
Essentially MailMyWeb allows you to surf the web in your e-mail client. What could be cooler? Registration is required. MailMyWeb is currently in public beta.
