Have a "check"?
For example... I would have a dictionary with the parameters to sent to the POST.
params = {'text':'how are you?', 'subject':'hi'}
then I would have
opener.open('theurl',urllib.urlencode(params))
The question is...those parameters work well with text-boxes, since I just put the value in there. How about radio buttons? How do I signify which is "checked"?
