Installing Drupal

During the installation of Drupal-7 a Site Name and Site Email Address is required. My site is on a home network behind a router which connects to my ISP wirelessly and isn't in a "domain".
Can I make up a name for the Site Name and use anything for a Domain Name?
For example: Site Name = mygateway and Email Address = xxx@mygateway.org
Or can I use any thing for the Site Name and an existing email address I have e.g., xxx@gmail.com, for the Site Email Address?

Hi I hope some one can help me, I have just started to use Drupal after updating my server.

I am running ubuntu server 10.10 with LAMP, Bind and e-mail on it. I have run the Drupal install command and can log in to the site that was created. but i need to be running it on many site that are on my server, the problem is that people online are talking about uploading the Drupal file to the web server. please can some one help me.

if I do have to copy the file where do I find them

I'm in the process of creating multi-site with one db, and have a few questions..

If all sites share one db and a person does a search will it search all of the db, or just the prefix for that site?
The other thing I'd like to know is how can I share the user across all sites. So the user can login on one site and it will fall over to the rest so there are no multiple logons.

When doing the shared db...do I need to drop what is being shared and create a new db for that table?

I looked at the settings.php and dont understand all that well

So in my settings.php I have
$database = array (
'default' = >
array(
'default' =>
array(
'database' => 'dbname',
'username' => 'name',
'password' => 'PW',
'host' => 'localhost',
'port'[ => '',
'driver' => 'mysql',
'prefix' => '',
),
),
);

So am I suppose to place the code below somewhere in the code above, or is it its own life form?

To provide prefixes for specific tables, set 'prefix' as an array.
* The array's keys are the table names and the values are the prefixes.
* The 'default' element is mandatory and holds the prefix for any tables
* not specified elsewhere in the array. Example:
* @code
* 'prefix' => array(
* 'default' => 'main_',
* 'users' => 'shared_',
* 'sessions' => 'shared_',

I have book Drupal 7, David Mercer, Packt Publications, this means i must install 7, yes? well, Drupal 8 come out, if no when? may have both drupal 7 and drupal 8 in one pc?

My book says install drupal local host, this means install Development releases and NOT Recommended releases OR...DOES NOT MATTER WHAT?

WELL, after install local host if same files uploaded to a live server, these still will function?

I have mysql Server version: 5.1.41-3ubuntu12.9 (Ubuntu) installed on ubuntu 10.04 and the drupal 6 installation wizard doesn't recognize it. In the browser it just says

Database configuration
Your web server does not appear to support any common database types. Check with your hosting provider to see if they offer any databases that Drupal supports.

P.S. The packages installed are mysql-server mysql-common php5-mysql and phpmyadmin

Where are located drupal system logs?

any ideas what could be wrong?

A simple question, I think. The instructions say to move the un-compressed files "up one level" to the web directory.
