I have a CMS to which many people can possibly provide data. So, I would want to include all the users who have contributed the data for a node by adding new data or moderating existing data, because everyone who contributed for a node deserve themselves to be undersigned. Right now, only the first person who creates the content would be the rightful author.

How can I achieve this?

I have googled but could not get much help. The closest I could find was this, which still goes unanswered. I have checked Entity Reference module but I could not get it to auto-fill the author whenever a user edits an existing node.

I have automatic revisions enabled, which means I do have the information of each author for a node who have contributed. But how do I pull each author out of the revision information and display the collection of all authors & contributors in a nice manner at the end of each article?

Please help me find a solution, I am not that well versed with PHP programming.

Thanks & Regards,
