On first launch, WordPress prompts you to input your MySQL database username, password etc. Then I can start working from dashboard.
Is it possible for WordPress to have more than one database?
If yes, what is the possible example for having 2-3 databases? When would you need more than one db?
Or the working rule is: one blog - one db? If you have 2-3 blogs, can you manage them from the SAME dashboard!? And each must of course have 1 db?
