Post installation

I am trying to create an 'About Us' section with several book pages in it for the prev/next navigation and want the urls to match the book pages path. I set [bookpath].html as the placeholder in pathauto and then created the top-level book page (About Us). But, the alias shows as just .html

I then changed the pathauto placeholder to [bookpath]/[title].html, but with the same results. Then tried putting just bookpath.html (the way you need to put flexinode node names without the square brackets in pathauto), but the output was bookpath.html

Is there any way I can add an authoring options area to a content type that doesn't have it? For example when I create galleries, there's a posted by anonymous and a timestamp. I don't know if it's Image Gallery or Import_Image that's doing it but neither has any setting for authoring options. I would prefer if just the image showed in the gallery, without a timestamp, posted by name, or filename.

Are there any random image mods that have more features than the default block that comes with (I think) image.module?

http://example.com/siteA and http://example.com/siteB are two different websites. I would like both to be served thru a single Drupal engine.

I have configured Apache such that example.com document root is in /home/html/www

After reading, http://drupal.org/best-practices , I am still not clear on how to structure the directories. I have at the moment:

/home/html/www/sites
                              /default
                                  settings.php
                              /example.com.siteA
                                  settings.php
                                  files
                                  themes
                                  modules
                              /example.com.siteB
                                  settings.php
                                  files
                                  themes
                                  modules

But when I browsed to http://example.com/siteA or http://example.com/siteB , I will get these messages:

Unable to connect to database server

This either means that the username and password information in your settings.php file is incorrect or we can't contact the MySQL database server. This could mean your hosting provider's database server is down.
...
...

I have made the necessary changes to reflect database settings in /home/html/www/sites/example.com.siteA/settings.php and /home/html/www/sites/example.com.siteB/settings.php

I have read much in the forums about multi site single sign on between sites..
According to what I read people are recommending to share a single database using table prefix.. etc.

But what I dont understand is why not use the drupal.module and create a central authetification location.... I mean, not linking directly to drupal.org/xmlrpc.php server to for example to :

mymaindomain.com/xmlrpc.php

and use this subdomain only for user accounts creation.

Then..

Hi all,

I'm trying to implement a register/login-to download functionality. In particular I want to
restrict download a videos.

I've setup the video module and the Logintoboggan module and I've given permissions to
the anon user to access the video node, but not to download.

So, as anon user, I've "» login or register to play video or download".
With the Logintoboggan, I've checked the immediate login option.
