Drupal 7.x

Hi,
i have install different site with multisite, and it's ok, in different database ...

I have a question:

I can install different site, in the same database and in the same table? Creating a different instance for each site?

For example:

The installation of Drupal 7 create about 75 table...

I have 6 site in the same database:

the number of tables is about 450! And i not install any modules...

I can keep the same number of tables while having 6 sites?

My system environment:
Windows XP Professional SP2 32 bit
Apache 2.2
MySQL 5.0.89
Drupal 7.0 Beta 2
Apache and MySQL tested run OK and have hosted another website which works normal also.
-------------------------------------------------------------
I follow the manual to start the install script. After entering the database information and click continue, I got a httpd.exe error message that says "0x0179249a" "0x000000000" memory cannnot be "read" then the installation process stops.

As topic really. I've spent the best part of an hour searching and experiment to no avail. I have some incoming RSS feeds which I've added into the aggregator. I want these to be displayed in various blocks, but don't know how to get seperate feeds into seperate block. Help!

Thanks

I added a menu to the top of the page where the home tab is, I have other menus up there but I want to make these a separate page/link when you click on them. How do I got about creating these new pages/links? I am still very new to all this, started off w/ Drupal 6 and decieded to update to Drupal 7, can anyone help? Don't have much experience in doing this, please be very specific. Thanks.

In Drupal 7, with the text box for adding tags (field_tags, autocomplete term widget), how can I lengthen the text box?
We frequently want to add more tags in, and it would be easier and less error-prone with a longer box instead of scrolling over with the cursor.

Hello,

I have a custom content type (story) with a datetime field which determines if a story shows up in a the views that list the nodes of that content type. I.e., if the datetime defined for a node is newer than the current datetime, it will not show up.

My problem is that I have to go and empty admin/config/development/performance and click "Clear all caches" or uncheck "Cache pages for anonymous users".

I would like to keep caching pages for anonymous users, so I am looking for other options.

Any help is much appreciated, regards, Egil.
