Yes, I know I owe another double post - this project is becoming much more difficult as we enter the last 100 days. What should be the home stretch may be the busiest time of year for me. The double post will come later this week.
In the meantime, do you work for a school district that does not allow your students to have email? Yet, you still want to have them sign up for Web 2.0 utilities you have found in this blog or on the web? Why not give Dispostable a try? You generate a random email account that requires no sign-up. Keep that page open or write down the URL. Use that address to sign up for the utility of your choice. Check your Dispostable inbox for registration details or activation codes. That email will vanish in two days (or you have the option to clear it immediately). No muss, no fuss - just an easy disposable "e-mail" account.
