1. Fantasico doesnt provide Invision Power Board
To create a MySQL database, in cPanel there should be a 'MySQL Databases' picture and button, Click on it! Near the center/bottom of the page there should be somewhere where you can type a name of the new database (if you type IPB, the database will by cpaneluser_ipb). Once you have created the new database, go back to the IPB installation, and fill in the MySQL database name things, then type your cpanel username and then password. The prefix thing you can skip (doesnt make much difference). Now, the last bit is just for your Forum username and password (it will create it for you).
