How to move/copy a discussion board item in Sharepoint?

Question

How can I create a function that copies some item from one Sharepoint discussion board to another? Everything is quite simple except field name Posted By, MyEditor, and Editor.

If this is a one-time thing, you might look at using the Content Deployment API (there's a Content Deployment Wizard app that provides a UI for it).

Otherwise, you should be able to set the "posted by" by using something like this (assuming web is an open SPWeb and newItem is a discussion item):

SPUser user = web.Users["DOMAIN\\username"];
newItem[SPBuiltInFieldId.Author] = user.ID;
newItem[SPBuiltInFieldId.Editor] = user.ID;
newItem.SystemUpdate();
