Drupal 7.x

Hi, I wanted to create menu tree, for example:

Menu:
- menu-item 1
-- menu-item 1.1
-- menu-item 1.2
- menu-item 2

So the parent link for 'menu-item 1.1' is 'menu-item 1'
and if I tick the box 'show as expanded' for menu-item1 its children are displayed on the web page.

I am currently running drupal for my website (codtoc.com) but am becoming less and less impressed with the functionality of the forums and social intergration portion. I am not one to complain about drupal because I loved it until two days ago when I noticed the functionality of Joomsocial and some of the other joomla addon's. The themes for joomla are also much more impressive than they are with drupal (at least to my knoweldge).

Is drupal the right CMS to be used for a forum/social heavy site like I am attempting to create.

I'm running drupal 7 on a debian server with quad cores and lots of RAM. I'm a drupal rookie.

I have it running, but its not reliable. Some links never respond.

I have used profiles2 to modify the registration form to account for our primary users of the site. However, when new admins create an account, they are required to fill in fields that don't relate to them. If I create a new user as an admin, the modifications to the registration form are still there. How can I get around this?

I'm building a site with Drupal 7 and want to emulate the flipped table view as provided by Views Hacks. I tried to reuse the code as showed in http://drupal.org/node/174578 but this doesn't run " as is" on Drupal 7.

I modified line 11 to show "print $classes" instead of "print $class" but still get errors on other lines
(eg: on line 21:
foreach($row['title'] as $title):

error message is :
undefined index: title in include()

Is there anyone who knows how to make this code work in Drupal 7?

Full Drupal6 working code from previous post:( http://drupal.org/node/174578 )

  $row = array();
  foreach ($rows as $col){
    foreach ($col as $ltr => $value){
      $row[$ltr][] = $value;
    }
  }
  $first = TRUE;
  $element = 'odd';

endif;

if ($first):

foreach($row['title'] as $title):

endforeach;

  $first = FALSE;
        endif; //$first
        $element = 'even';
  if (!$first): 

Just wanted to get an idea of what you thought would be a better model - I'm starting a basic blog but I'd like to be able to add video content to it - I know how to add embedded video into an article post, and once I figure out how to get my Transcoders up and going I'll be able to host streaming video right from my web server.
