Tested a UNIX hosting account at gate.com. It doesn't look like a Windows account supports MySQL at gate.com.
Assume domain is called mydomain.com
Assume username is michaelh and the password they assigned my username is ABCabc123cba
Here's my wp-config.php settings:
Had to activate the MySQL database but the database name and database user was assigned by gate.com. I could change the password for the MySQL database, but as initially created, it used my username login password.
phpMyAdmin is not provided by gate.com. They direct you to http://www.phpmyadmin.net to download/upload/configure phpMyAdmin on your own (like you would do with WordPress).
