You might have a specific page that displays more information that the form.

This is an example (taken from http://www.etownhall.eu) that assumes that there is a Drupal node
that contains a cck field 'petitionid'.
This node is going to be used for the social networks promotion instead of the form.

This is an example of how to fetch content from a Drupal node (that contains a cck field 'petitionid')
You will want to customise it based on your configuration.

How to install ?
Create a custom template folder and copy this file into CRM/Campaign/Page/Petition/SocialNetwork.tpl
This assumes you are on Drupal, have installed the fb module (drupal.org/project/fb),
and in general, is very unlikely to work directly. Please consider this as an example,
and modify to fit your specific configuration.
