To post a Petition onto I~Promote in order to give it some more exposure:
Click on New Topic
Enter the Name of Your Petition in the Subject
Enter a message if you want to let people know more about it before they click the link and don't forget the URL. This is the link at the top of the page which has your petition on it. ie.
When you copy the URL, it usually comes up red in the topic box until you post it when it becomes blue.
I hope this helps and isn't too 'condescending'. I've tried to make it as simple as possible. My rule is: "If I can understand it, anyone can".
