After searching on Google for several days, I found instructions on how to change the database prefix AFTER installing vanilla....
That's pretty useless in my honest opinion. It's like building a car with an engine that doesn't fit only to take out and fit a new engine after it's off the assembly line and at the car dealership, or something.
Every other open source script with an installer seems to have the "database prefix" area on the setup/install page.
How do I INSTALL Vanilla forums with an alternate prefix?
Thank you for your time.
