Customer Cases - No Help from BC

Hi All,

I am currently working on our new website and thought it would be good to integrate the BC cases and ticketing feature into the website which will allow clients with issues to raise them through there.

Link for website: http://www.6sm.co.uk/1-template-test

I have succefully setup the feature and it is all working great however I have a couple of things I would like to understand better.

1. Can the cases which are submitted by Users (sometimes many for one company) be automatically assigned to the company instead of the individual?
   
   We work on a maintenance contract or time basis and want to be able to show the client all the issues we have dealt with from one location. The case should be linked to the company in order to build a client profile, people move jobs sometimes so we dont want the cases to become lost in the process.
   
   
2. The email that comes to Support Level one has several fields empty, please see image, where do I go to auto-populate these as before the email arrives it is already assigned a case number.
   1. How do i add a subject field and where do I update it so it puts it into the email?
   2. The form is repeated 3 times in different areas, where do I change this layout?

Hope I have made sense and someone can point me in the right direction.

Many Thanks

Asad Ali
