I am using SharePoint Server 2007 with Windows Server 2008, using publishing portal template. I have a list in a page. I want to set permission to allow all authenticated (i.e. non-anonymous) user to be able to add new item to the list, but not allow them to change schema (e.g. add a new column, delete a column or create a new view for the list).
What kinds of permission should I set and how to set?
thanks in advance, George
