Deprecated - Drupal core

I have just successfully installed Drupal, added multiple pages, blocks, changed themes without any problems. However I cannot figure out how to have multiple stories on a single node. Every time I try to add a new story I can either have it promoted to the front page (which I do not want to do) or have the story go to it's own node. My question is....How do I have multiple stories on a single node, where do I specify this? I do not see an option to specify what node I would like the story to appear on.

Dries has done some benchmarking..
The discussion on the development mailing list boils down to:
We've got to improve non-cached performance if Drupal wants to remain competative.
(because its easier for other products to improve their caching and catch up on the front).
So where do we start? What does the code profile look like? Where are the bottlenecks?

Attached are a couple of profiles from my laptop serving the default front page (/node) from localhost.

I think this topic may be interesting for developers working with mobile devices.

There is a nice framework called WALL (http://wall.laacz.lv/) which was designed to create mobile independent content (you don't need to worry wheter user's mobile support XHTML or WML or anything else). There are also many other abilities of this framework.

I would like to build a Drupal theme which will be based on this framework in order to be mobile independent.

Is somewhere description of standard tables in database. Description of items, etc.

All table are created and I have created a "template" site / content (so that new sites get "launched" easier) and then copied the pre-filled-with-sample-data tables into multiple instances of the same database with locations (ie: chicago_, sanfran_, boston_, etc). Everything seems to be running okay - except the editing / creation of nodes.

Nodes that already exist, if I try to edit (and turn "create new revision OFF") come back fine. Creating a new node, or editing a current node node and checking "create new revision" gives me the following error and the page remains unchanged (or uncreated).

Duplicate entry '5' for key 1 query: INSERT INTO chicago_node_revisions (nid, vid, title, body, teaser, log, timestamp, uid, format) VALUES (2, 5, 'this is a chicago page', 'without using the revisions', 'without using the revisions', '', 1155409857, 2, 1) in thesite/chicago/includes/database.mysql.inc on line 120.

The following is the setup of my tables and site reguarding what is shared:

$db_prefix = array(
'default' => 'chicago_',
'users' => 'shared_',
'sessions' => 'shared_',
'role' => 'shared_',
'profile_fields' => 'shared_',
'profile_values' => 'shared_',
'authmap' => 'shared_',
'sequences' => 'shared_',
);

I was told I might have "messed up" my sequences table (not sure how, all I did was rename it to "shared_sequences") but here is the content of it.

the default name is 'anonymous user' and 'authenticated user'. They are locked. Can I change their name? maybe visitor and member or others...
