my problem is that i cannot make the modules css field to work. simplenews is working correctly, altough simplenews templates 'header' and 'footer' capabilities are both working, however, wathever i type in the 'CSS' field for my newsletter it does not have any effect on the sent e-mails.
even the example provided in the documentation is not working.
i don't understand the thing totally, what does that mean that simplenews template includes my themes css? i can refer to classes defined in my themes style.css in the body of the newsletter? even this is not working.
