I'm a newbee to Smarty and I've spent half a day trying to figure it out but still can't. This is the question that disturbs me the most: Where are all the PHP variables and their values stored?

For example, if I want to remove 'default' sorting feature for products sorting, I know I should find an array called 'sort_fields' and remove 'default' from that array, I just don't know where to find it. Would somebody please help me with this?

Also I don't know where to find all the variables. Like I know that for the telephone numbers the variables are '$config.Company.company_phone' and '$config.Company.company_phone_2', just don't know how to insert the company's email address?? I found it by accident that it should be '$config.Company.site_administrator', but I really want to know a proper way to find it. In which file are these variables stored?

Thanks very much!!
