Post installation

My search-fu is weak so please excuse if this question has already been answered.

I've configured my Drupal site to use clean URLs already. Now the problem I am running into, is the following.

When I create a new menu, I can add items wthout any trouble. When I link to pages of my Drupal site everything is fine. If I link to external pages, the menu item won't show up in the menu block. The menu title shows up but not the link (menu item).

It does show up in the menu administration page, and if I click on it from there, it also takes me to the requested page.

Hello,

I have a bunch of nodes which are published, but are not promoted to the home page. Rigth now, their creation timestamp is set to when I want them to be promoted to the home page.

So, basically I would like to to slowly, automatically promote them when their published date becomes "current". Before then, they should be accessible but NOT promoted to the home page.

I found the "scheduler" module which is able to set an article as "published" at a later date. I am not sure if scheduler would work for me, or if there's an easier way for me to do this in Drupal.

After spending a week trying to workout why Drupal was rendering my Mathml (www.mathforall.co.za) all wrong I have some answers . Getting it to work was not that hard. All I had to do was change functions in the common.inc file. It's really and ugly solution for now, but it works. As soon as I get some time I will tidy it up.

Here is what I did:

1) Drupal sends content=\"text/html mime type out be default. I think they do this so that M$ IE (a primitive browser) will not explode when it visits a Drupal site. So I changed Drupal to send application/xhtml+xml mime type to some browsers. I added the broken_browser() function based on code I found at:
http://hacks.oreilly.com/pub/h/2916

function broken_browser()
{
$agent = $_SERVER['HTTP_USER_AGENT'];
$broken = FALSE;
$broken = $broken || (stristr($agent, "msie") && !stristr($agent, "opera"));
$broken = $broken || stristr($agent, "microsoft internet explorer");
$broken = $broken || stristr($agent, "mspie");
$broken = $broken || stristr($agent, "pocket");

if ( $broken ) {
$head = "\n";
}
else {
$head = "\n";
}
return $head;
}

2) I changed drupal_get_html_head() to send a mime type determined by broken_browser().

I have read the tutorial on theming flexinodes via creating a node-flexinode-n.tpl.php file here http://drupal.org/node/45475. I am now having some trouble understanding how to customize this theming for a teaser vs. for the actual node. I want to display only some of the fields in the teaser yet still have control over how it is displayed. Can anyone help me out?

I need to include in all my pages the filename that is printed in th URL bar. I suppose I must to change the xtheme but I don't know what to script.

Please Help.

Does anybody know how to config the ldap_integration module so it only looks to LDAP for passwords? Any tips or advice would be appreciated. We change our passwords every 60 days and we'd like them to stay in sync.

Thanks
