You will need to create a database. Hopefully, you have CPanel, or some kind of Control Panel to do so. If you do not, then that is something you will need to talk to your host about.
If you do, find "Create MySQL Database", or something close to it. Create a database, and then create a user and password. After you create the user and password, add the user to the database.
Now go back to install PhpBB. When it asks for your database name, put ACCOUNT_DBNAME. (So, if your hosting account login is dog, and your database is cat, it would be dog_cat). The same with the user. The password is just the plain password you put in.
Hope this helps :). If you get too frustrated to install, and just cant handle it,
http://vizionbb.net/ is a great modified PhpBB resource for remotely hosted modified versions of PhpBB. :) Good Luck!
