Pay attention to the "edit" section of that article. When you call the
construct_edit_toolbar('', in your template, your first argument will be a blank
'',.
Change the '', in the template to what you want to display in the editor...
Code:
construct_edit_toolbar('Rating (/10)
Price:
Comments: ',
Can you dig it? (Note that the above code is only a small sample of what should be in your template. You will need to modify it with some if conditionals so that it doesn't display on every single discussion area).
