Drupal 4.7.x

I recently installed drupal 4.7.0 using my host's installer script, and all is well, except I installed it to a sub-folder, and while I want the files to stay in that sub-folder, I want all of the links to be based on the main domain....

What I mean, is the following two pages are the same:
http://www.geekbrownbag.com/gbb/?q=node/3
http://www.geekbrownbag.com/?q=node/3

I had several drupal installations on my server (actually, a friend's server). Everything was working fine until we updated our PHP from Perl 4 to Perl 5. Now, when a user logs in, the session appears to expire almost immediately. For example, when I log in, I try to get to the admin panel, and I get an error that I'm not permitted and I'm no longer logged in.

The only thing that has changed on the server is the upgrade to Perl 5. Now we need Perl 5 for other projects, so downgrading isn't an option.

What can I do to fix the problem?

I would like various modules I use like the event module and the contact module to use custom themes. Does anybody know if this is possible?

I am trying to implement '#autocomplete_path' on a text field in my module.

$form['foo'] = array(
'#type' => 'textfield',
'#title' => t('First Name'),
'#size' => 12,
'#autocomplete_path' => 'hello/auto',
);

I posted this in the wrong forum before:

I then have a modified function from user/autocomplete in the user module.

function hello_world_autocomplete($string) {
$matches = array();

I want to break up my events into sections. So citya-events.html will just go to events under the category City A, cityb-events.html will just go to events from city b and so forth. I'm using the events module and that seems to work for most of what I'm doing but not this. If I go to events from citya for the events dropdown on the main events page I get an URL with date embedded into the url > /event/2007/05/02/table/all/2. Same for other events /event/2007/05/02/table/all/3, etc...

On my website : http://www.nitrogamers.fr

i want to change the menu made by links for example : Accueil, etc...

i wan to put buttons instead of simple links.

Can i change links to button? is it possible? if it's possible how can i do that?

Thx for answers.
