All kinds of bugs with SQL databases

[nemiux]

I was creating a joomla site in my localhost, cause (no offense) trying to do install and create it here is slow as hell. Well I'm done, and I want to upload my files. Here starts the problem. I can't remember from when but in my account I have 3 databases already. 1 called forum (nemiux_forum actually, thats my account name), other forums, and the third nemiux_jooml71, from trying to install it from here. So I can't create anymore databases, but I can't seem to be able to drop them either! I uploaded sql files to nemiux_jooml71, so I guess it will fit after i change my joomla configuration, but I don't know the password to my SQL accounts, I also don't know the server. The wizards suck, they can't create a db but there's no error(I think they cant cause the limit is exceeded).
So mainly what I need to know:
What is SQL adress?
Where do I find my password?
How do I drop(delete) databases?

Thanks.

cPanel --> MySQL Databases
is where you can delete/create databases.

cPanel--> phpMyAdmin
is where you Import an SQL dump into an existing database

The password you use on a specific database is the password you gave a specific database user you created via cPanel-->MySQL Databases and then attached to the database.

Any configuration for a script-database connection uses 'localhost' as the address
