You'll be wanting to get to grips with Privilages.
On the phpMyAdmin Home page, there's an icon called Privilages. Have a look in there, but take great care!
Note that Privilages can relate to users and/or databases and/or tables.
Lots of reference info at
http://www.mysql.com/ and in particular
http://dev.mysql.com/doc/refman/5.0/en/ ... ystem.html
Other ways of creating databases
Again, check
http://www.mysql.com/. When you start to get familiar with MySQL, I think you'll see that phpMyAdmin does the job nicely.
Otherwise, maybe have a look at SQLyog.
