One problem, Peter, is that when I joined it was not made ABSOLUTELY clear that if there was *any* text left over from WP that had been written by someone else, then the WP checkbox *had* to be checked. The attitude seemed to be, oh, well, you wrote 75% of the article, no need to check the box....
My recollection is that Alex Stos had a program that compared all articles looking for phrases that might match the WP article so we could make sure that we weren't using anything from WP. If there was even one sentence, we checked the box (unless it was common verbiage for that subject). Initially, most of the authors were the same people that began the articles on WP, but were dissappointed by the changes made at WP, so they brought them over here and returned them to their original state. All they had to do was prove their ID on WP and I would then check the article history on WP to see. If they were, then we used the WP template to explain and document why we DID NOT have to check the box.
This was all performed during the BIG CLEANUP... Remember, we started as a total mirror of WP, but then deleted all articles that we did not want and then had to go back and check the box (if necessary). That process was completed using Alek's script program. Then others began importing before we realized that if an edit was not made when you clicked the WP checkbox, it would not be saved. If there are articles left that have not been checked, they were either more recently imported or the box was checked without making an edit.
