Module development and code questions

I have three drupal vhosts, three different folders under 'sites' with three different settings.php
Each settings.php has this line:

ini_set('session.cookie_domain','.mysite.com');

which (after reading countless forums) is given as a solution for sharing cookies accross different vhost names. However, once I added this line to the settings.php I can no longer login at all....

Dunno if this is the right category for this post, but....

I installed Multiflex theme to my site www.dyrepass.com, it looks nice, but there is two small problems:
* Acidfree albums dont fit with the content, some albums "dissapear". Guess I either have to edit the albums module to fit the size of the content, OR edit the theme size to take the full page. How do I do this?

* Some text is to small in the multiflex theme. Easy way to help with this? E.g. Login text.

Hello, I'm trying to make a form where an item has a checkbox and when selected they can enter data into a corresponding text field. My specific case is that I have a list of items that can be requested and I want to add a field to the list that asks how many of the checked item they want.

Is there a way to currently do this in the webform module?

Hi,
