|Yes, but it's a bit tricky..
To install the second (or third, fourth, etc... there's no limit!) WordPress install in the same database as your first you first go install it as usual, choosing the same MySQL database you already used once.
But this time, after you get the email telling you the URL to go to to finish your install, first find your wp-config.php file in your WordPress directory and edit it. Find this part:
Change 'wp_' to be anything else (because your first WordPress is already using 'wp_'). Maybe choose 'wp2_' for example!
// Change the prefix if you want to have multiple blogs in a single database.
$table_prefix = 'wp_'; // example: 'wp_' or 'b2' or 'mylogin_'
Now continue with your set up as normal and you'll be all set to have two WordPress blogs running off the same database!
