for mysql you have a database username, password, and each database has a database name.
It's asking for your username and password and what you want to name the databae..
I forgot what your username is but the password is your zymic password for the site.
i think the username is like sitename_subdomian_extension
like if your using 99k.org as your subdomain it would be sitename_99k_org i believe
something like that

Sorry if that wa't much help
