Deprecated - Drupal core

I am using CivicSpace 0.8.0.4 and I've discovered some strange behaviour.
After switching language for example German the site displays German language,
but if I browse the site the site changes back to default language (in this case english).
I still not figured out how drupal works, but this might be a PHP session problem.
Could somebody tells me please which files are necessary to edit ?

i was curious to know if any developers would like to see a little more functionality added to the database abstraction layer...

I recently noticed that DocBook export has been added to the books. Do you know if it is possible, or has anyone looked into importing docbook content into Drupal? I thought I would check and see 1 if it is possible, and 2 if anyone has an import script to do such a thing (or something similar that i could model a script on).

The menu module currently outputs:

<li class="leaf"><a href="/team" title="" class="active">team</a></li>

There would be more css possibilities (ie Douglas Bowman's sliding doors tabs) if the class="active" was moved to the <li> like:

<li class="leaf" class="active"><a href="/team" title="">team</a></li>

I would love to see a WYSIWYG included with the installation.

* More attractive to new users
* It's a killer feature
* Also add an image mannipulation module for nodes to work with the WYSIWYG
* Running f.e. TinyMCSE with multiple db/webs in one codetree is problematic and imho its pointless to create one database per webpage just for TinyMCSE settings.

It's not just that I'm lazy and can't fix this myself. This would help new users alot and attract more people to Drupal. I know HTML but f.e. my Mom doesnt and most of the people who use CMS systems don't.

I wanted to disable the album menu item and og menu item, and when I did the subitems that are dynamic came out into the main menu. So I hacked it and am using a function to see if the main menu item is visible in menu. Let me know if this is the way to go and i'll submit a patch for menu.inc as it is working for my purposes.
