I have a SharePoint list whose items are created by members of a group of ~700 people. The content of these list items needs to evolve over time but we need to limit edit privileges so that only valid changes are made. Bottom line, this means that our permissions are set up so that only the creator of a list item can change it.
Problem with this is that occasionally list item creators leave the company or change roles and we need to re-assign editing privileges to another individual. In other cases, we would like to grant editing privileges to several people instead of just the creator. Is there any way to change the "created by" field on a list item so that a new person can become the editor? Even better, is there some way to set up the list so that edit privileges are can be granted to a short list of people in addition to the creator? Finally, is there some more clever solution than using "created by" to determine who the editor is?
Thanks in advance for the help.
P.S. We're on SharePoint 2010 and will be migrating to SharePoint 2013 in 8-10 months.
