How To: Enable Username and Password Autosave in Safari

This is dumb.  I almost can't believe I'm writing this, except for the fact that the default settings for Safari are so ridiculously stupid.  By default, Safari will NOT ask you to save your username and password for any account on any site you visit.  Period.  Want to turn it back on?  Here's how:

1. In Safari, go to FILE >> PREFERENCES >> AUTOFILL
2. Check the USERNAMES AND PASSWORDS checkbox.

That's it.  Done.  Seriously.
