Module development and code questions

... following on from last months discussions I still seem to have no CVS account so I gotta go it alone.

How do I output these two form items on the same line? I can't get the automatic line break out.

$form .= form_select('Manager #2', 'mid2', $mid2, $options, NULL, 0, FALSE, FALSE);
$form .= form_select('Manager #3', 'mid3', $mid3, $options, NULL, 0, FALSE, FALSE);

TIA,
Billy

I am working on my own gamereview module. I would like to override the default teasers that show up on the front page so as to show the publisher, developer, rating, etc. from my gamereview database, and also to give them their own css (right now the teasers all show up as 'div class="node"' but I'd like them to be something like 'div class="gamereview"'. Basically I want complete control over how the teasers are displayed, including the title. I can see that there is a $teaser variable passed into hook_view() but I don't know if it does the right thing or what to do with it.

I have a module with node type 'exemple' and i want to hide the preview button only for this 'exemple' node-type.

Can i use an alter hook to do the job ?

I tryed to use the following hook without success :
exemple_node_form_alter ....
exemple_form_alter ....

both are not run!

I'm writing an implementation of jsDomenu for use with the menu tree not the taxanomy tree that the current jsdomenu implementation works with.
I got it to work as extended theme functionality, but I'm totally stuck now that I'm trying to make it a module.

To build the javascript code my module depends on the 'visible' part of the array from the menu_get_menu() function.
So my question is: What hook to use that is called early enough for inserting javascript code with drupal_set_html_head() and late enough to get the content of $menu['visible']

I have many vocabularies, but only one (visibility:internal|external|both) that affects whether access should be given to a node.

Am I misreading taxonomy_access?
... or does this situation cause two problems:
1. the 'edit category permissions' page is huge
2. the resulting permissions can only work if visibility is the *only* tag added to a node. (because if you add another tag, the node permissions are affected by it)
