Install for multiple databases

Why use a new database for each theme? One of my local installs has about 2 dozen themes on it at any one time.

That’s not really the point…

Well, what is the point of running a new db and install just for a new theme?

I can do that, but again, not the point.

I’d appreciate you either helping to answer the question or not replying at all.

Yes, just change the details in the wp-config.php file.

And re-run the installation.
