Drupal 7.x

I'm pretty new to Drupal, but managing to muddle through.
I'm still learning php, but can follow directions.

At the moment, I'm looking at setting up a small site for my organization.

The site needs to have several Blogs that members of the organization can post to.
For instance, one blog where members post recipes, on where they would post restaurant reviews, one with kitchen appliance reviews, and so on.

Each member needs to have their own user name, and be able to submit posts to each blog.

Hello,

I have a tiny problem that is causing a huge headache for me since I've been unable to figure out what exactly is causing the "push".

My problem is that I have 3 main menu buttons, News, Blogs and Forum. Whenever I go into the "Blogs" node, created by Debut Blog, the layout gets pushed a few pixels to the right. I find this odd as it doesn't suddenly take information from another css and the template file doesn't have anything in it that would change on the layout itself. It doesn't happen when I click News or Forum.

I have no idea what to check now.

What is the best way to implement Journal of Economic Literature (JEL) Classification Codes (http://www.aeaweb.org/jel/jel_class_system.php) using the taxonomy system of Drupal? For example the code "A14 - Sociology of Economics" is just A14 on the CSV file that I wanted to migrate from.

I was building a site in Drupal 6.19 on a webhost server, then they allowed me to upgrade to 7 via a simple script. I did so and then installed the Drupal 7 version of the theme (Marinelli). The menus are sometimes okay, but sometimes entries disappear.

Hello,
I've created a custom field for my content type and want to display the previews on a view page. On my normal content page I can access the variable with $field_name[0]['value']

Array
(
    [0] => Array
        (
            [value] => 3
        )

)

However, on the View Page the Array looks like this:

Hi all, I just installed Drupal... something i've never used before.

I'm wondering if there is a module out there or an easy way that I can:
Allow users with accounts to create content (by filling out a few custom fields) and submit them to the main website (which is viewable by all - auth and non-auth alike).
Perhaps if there is a moderation ability to make those changes or submissions go to administrator review, would be a big plus as well.

Suggestions how to pull this one off?

Sincerely,
Just started
