I believe this is for using multiple databases.
If you are only using one db, focus on the settings in the first 17 or so lines of the config file.
Line 19 being where you set the option of using multiple db's, then configure them with that array.

it says to use different username and database
for each array

after editing : what next?
http://www.mywebsite.com/wpmu/ ?

i could realy use some help here! please!!!!!!!!

when i try to use http://www.mywebsite.com/wpmu/
it tells me ,cant find database or something like that

Question: Are you using one db or multiple?
if you are using one, then dont mess with this. If you are using multiple, then your gonna have to wait until one of the volunteers here on the board that uses or knows about using multiple dbs can post a reply.
First things first, are you using one or multiple?

just one, mysql db

Then you don't have to touch the wp-config file at all. The installation is nothing like the regular install for WP. :)

so how do i get around the message i get ,can't select data base from http://www.mybebsite.com/wpmu/
