i want to add a new field email to plone.app.discussion comment for anonymous users . I have searched in google and found two approaches.

Approach1: using quintagroup product "quintagroup.plonecommments". With this approach my plone is getting crashed.

Approach2: Following the procedure given in the URL : http://packages.python.org/plone.app.discussion/howtos/howto_extend_the_comment_form.html. This approach is not working.

Can anyone help me with any solution for my requirement.

Traceback of Approach1:
