  == Before the Play ==  An editor has been reinserting unsourced information that was challenged in part because of its lack of sourcing. Please keep in mind that WP:BURDEN stipulates that material that was removed due to sourcing concerns should not be reinserted without any referencing. BURDEN trumps WP:PRESERVE. I would also remind editors of WP:BRD - the matter should now be discussed here before additional changes are made. Thank you.
