New Post: New to use Composite C1

Hi All,

Today I just installed composite C1 to play around today and found it's very in structure and easy to quick self-learning.

As my project requirement, I'm wondering if I can do with this CMS engine or not and how as a quick guide.

1. I need to create an intranet site which user account linking with window domain user account. So the user doesn't need to sign in again. (I guess I may need to buy an add-on Active Directory authentication, right? That's fine.)
   
2. I need to create custom features into this web application also, which will be staff contact management, noticeboard & news event, and document management system. Can I create my own App_Code class and specific web forms, apart of CMS engine? I saw that all the CMS pages will go to rendering page (Renderers/Page.aspx) only.
   
3. Based on my own custom features, I have to create user roles to set which user can manage document, contact list, and so on. Is it possible that I can use CMS System/Users and Permissions? Or can I use 'System.Web.Security.SqlRoleProvider' from aspnetdb integrated with user account (I have to set as authentication mode='Windows' also, I think.)
   
4. Can I change or customize text editor control?
   

Maybe somewhere in the documentation, but for a quick getting to the point, the experts here may help quickly.

Any guru response will be great.
Thank you all.
