SharePoint Manger 2007 For Adding Customized content Type

Hello All,

First let me explain, what is content Type? Its FAQ and very important to understand,
A content type is a reusable collection of settings you want to apply to a certain category of content. Content types enable you to manage the metadata and behaviors of a document or item type in a centralized, reusable way.
for the exact definition visit

For Customizing the New\Edit\Display Forms of Custom List
use SharePoint Manager which can be downloaded at codeplex
its a great tool for customizing content Types
