User submitted posts question

Hi all,

I want to create a website where users can edit my posts and make a complete website as possible.
What I am trying to do, working with Wordpress btw. :

- I create like 500 pages of content about, for example hats.
-User visit the website, has an interest for red hats and decided to complete the article about red hats.
-User clicks 'edit article'
- User gets an form where everything is devided into subcategories. For the hat example:

- Colour:
*What the post already is saying about colour is displayed here so the user can complete it*

Price:
*What the post already is saying about price is displayed here so the user can complete it*

Etc.

When the user made a new paragraph he can send it to me so I can approve or reject it.

I know users can add posts through plugins and user roles. But is it possible to create such sub categories? I've seen them on other websites but am not allowed yet to posts links.

Thanks in advance.

What you're describing sounds more like a wiki and a wiki might be a better option than WordPress. If you are adamant about using WordPress, look for some nice wiki and/or BuddyPress plugins that might provide the functionality that you need. Still, I think it would be much easier to do using a wiki.

Well I really like the look and feel of my website and I'm sure the wiki thing will ruin my site haha. But thanks for the answer
I already installed buddypress and I know it's possible to let users edit my posts. But to change every post into subcategories I can't find yet...
