Is there a way to limit the "edit item" permission in WSS 3.0 to only allow a user to edit his own documents or list items? We need the ability for a user to edit only documents/list items he creates – NOT items that someone else created. So, essentially we need a sub-set of the EDIT permission as well as ADD.
Is this possible in Windows Sharepoint Services 3.0? Is there a way to create custom permissions in code or a feature?
