Post installation

I would like to make a theme for my website. I have experience with html and I understand what php and css are but I have never written any. I am reading the handbook and it says:
"# Create your own Theme.

Many Drupal sites will need a more unique look than these pre-built themes can offer. Therefore, many developers will want to write their own themes. Theme development requires a working knowledge of HTML/CSS and possibly some rudimentary PHP depending on the complexity of your theme."

I want to add more fields on register form . Is there any possible way to add or can I customize it ?

Hey,

I just started using Drupal, so I'm sure this is a newbee question.
I have my Drupal site all running with the Pushbutton theme as default, then I installed the RDC template (and template engine)

Hi ,

I want to use civicrm profile page for a user for its "my account" page rather than drupal's existing one. As i found civicrm has better profile page than drupal. But when i am trying to change it using administer>>menus it is saying it is locked. Any idea how to unlock it and what should be the possible changes i need to make in url.

I have been searching through all sorts of vocabulary and taxonomy posts and even tried the vocabulary list module, but I cannot get to what I'm wanting. Basically I want a page that shows the description I put on a particular vocabulary and then lists the various terms under it. A node count would be nice also. This seems like something very basic to me, but I cannot figure it out. At this point I'm considering just using a php snippet page, but it seems like this should not be so difficult.

I want to setup a community just like createbits.org, but I'm new to Drupal. I'm wondering could you tell me how to do this:
1, everybody can have a blog (done)
2, everybody can post his/her blog entry without approval on his/her blog (done)
3, if he/she wants to recommend his/her entry to the homepage(index), his/her entry will be in the queue and wait for our admins approval (key question, don't know how to do)

Thanks :)
