Thanks, prof. You're an educator. Twatter links are never necessary. Little observation: They let me scroll endlessly when I'm signed into my Google acct but only let me see the first few messages when I'm not. (Box appears and wants me to create an account) P.S.: Nice Addon that signs you out with one click. https://addons.mozilla.org/de/firefox/addon/google-signout/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search
