I like the idea that they XP and writup totals are incremented before the transfer. I assume the 'editors' will have some sort of 'delete' button, which when clicked could decrement the original posters XP and writup. I wouldn't think that it is too hard to add the functionality to track the original poster in order to get this done. Even an add-on table which keeps track of poster, node, and date-added which can also have itself be purged of nodes in there for the last week (I assume if it isn't killed within a week, it is deemed OK).

Cheers,
