Drupal 7.x

Hopefully I am posting this in the correct section of the forum.

Do you know if D7 will allow us to edit each CCK field separately?
Purpose Wiki site style, node with many CCK fields, allow to edit each CCK field separately.

Hello guys,

I have read pretty much everything there is to read on installing Drupal 7 and still I am having trouble with the install.

The version of PHP is : 5.2.13
MYSQL Version is: 5.0

During the install process at "Set up database" I enter in my settings just like they are on 1and1 and I get this message in orange:

Hey guys!

First, I should shortly tell why I'm posting this message, in which conditions, and then I'll go further on with the details.
So:
- I'm French
- I'M working in an internship in a worldwide corporation that is also based in France, that does not want its name to be mentioned.
- They need some kind of an internal social Hub to coordinate their work and relations
- I love open-source
So that's for short; now let me get into more details :P

This company wants to acquire a much more advanced and user-friendly kind of intranet-based website, much more orientated on the "social" part than the intranet engine they currently use.
I'm also, currently, doing an internship in this corporation, in the IT service (you probably guessed).
They asked me if I didn't have any Idea on how to make their local network more dynamic, more transversal and productive, less formal than a simple project organizer (kinda like CVS, but for entreprise projects).

What they need is a mix that blends Facebook/Yammer, a wiki, blogging, news, and collaborative work.
I immediatly thought about Django, that's got a huge numbers of very powerful modules, all linked together into a stable base.
Although, there are some requirements, and that's why I'm here to ask if Jango can fullfill these requirements. They'll need:

Is it possible to have two different comment form types at the bottom of every post? For instance: one would be for regular comments whereas the other would be for 'revisions' to the current post. So that when i post something and a user finds something wrong with it, they can post a 'revision' comment instead of just a regular comment.

I get the following error when trying to install D7a6:

"Uncaught exception thrown in shutdown function.
