I must solve this problem:
I have a list in which there are stored some SPListItem. On this list a group(AllReplyers) has the "Contribute" privilege, so that everybody can add file. When a user add an element, i want this element to be modifiable only by him, and readable by the others..
I think a good way to do that is to "break" the item privileges, lower to reader the AllReplyer and add the single user to "contribute".. How can i do this programmatically??
Thank you very much!!
