We had three winners yesterday. Most of the responses were correct, but many were just too late. I hope to have an other contest either at the end of this week or early next week.
The answer to the past question, "When was the Google Toolbar first publicly made available?" is
The first publicly available version of the Google Toolbar was released December 11, 2000.
The answer can be found at http://toolbar.google.com/whatsnew.php3 at the bottom of the page.
Good luck next time!
