Its the first time I'm uding coppermine and I really don't know what to put on "MySQL Database Name" all the other info seems to be accepted except for this.
Please, help me!
you can't make the mySQL information up, you have to know it: either because you're running your own server (then you should have created the database, a mySQL user and password) or if you're webhosted, your webhost has to create it for you and tell you. If you don't know your database name and have no idea, ask your webhost.
