Setting up your extranet is really quick and does not need any IT skill :

• sign in to open your account
• create your extranet and pay for the first month (or request for a free KheperLite License)
• personnalize the page layout
• create the user list
  
• create your own menu

Then you can start creating your pages.

Later, you will be able to open a website for your project or workgroup, without any loss of information.
