Drupal 7.x

Hi there, I have some problem with views and the formatting of the results. I have one field created (user) in views.
Who is can tell me exactly, how I can display the results in row, one after one with a comma like this example?

user1, user2, user3, user4, user5, user6,
user7, user8, user9, user10, user11, user12,
user13, ...

I tried unformatted list, but it don't work. I I don't know, how to use the row and style settings to include a separator.
Pls write me exactly what I have to do step by step. Thank you very much.

Hello,

I wish display in a shop that works with Magento the regions of the site in the layout.

I created a node for the shop and now I want show this regions on my Magento's shop.

Is it possible to retrieve the regions (sidebar_left, sidebar_top, footer, ...)?

I have tried many things but without succes... :(
A exemple:

Using the domain access and i18n modules I have a site set up with four domains. Three are in English, one is in English and Japanese.

This is all fine but I wanted the Japanese domain to default to Japanese, so I have set that to be the default language in the domain site settings. That seems to work, but the language switcher doesn't seem to recognize it. Going to the home page, it is in Japanese but the language switcher offers '/' for English, which obviously links to the Japanese default and '/ja' for the Japanese... so I can no longer get to the English version.

I am trying to do something simple: if a status message contains a keyword 'points', have it display an icon in addition to the status text.

While there are modules that gussy up status messages, they are all Drupal 6.x =(

What is the most simple way to do this?

I've spent an hour researching and my current plan is to edit the templates.php file, and add a function as per

Is that a good idea?

I want to create a menu item that brings the user to the Create Node form for a specific node type (called "tower").
Thought I could do this with drupal_get_form as the page callback and the form_id as the page argument.

Here's my code in the module's implementation of hook_menu.

I need to implement multi site configuration in Drupal 7. I have a Drupal code base called example.com and two subdomains sub1.example.com and sub2.example.com in sites/ folder. I am using a shared database also.
