E2, when viewed in Internet Explorer 5 or higher has a secret feature. Here is how to activate it:
  1. Move your mouse to the bottom of the address box so it is an arrow, not a bar, but so it is still in it.
  2. Click and drag off the bar then back on. The page reloads.
  3. The E2 Icon is now where the IE page icon is!
Alternatively, adding the front page to your favorites will do it as well.

The gods only know what other secrets await discovery.
