For wikistats I would like to aggregate edit counts per editor for all wikis, so that we get a better count for how many people work on our projects. I checked several wiki pages on SUL, but am a bit unclear to where we are now. At the moment: can different Wikimedia wikis still have same names for different users? So that John or Jane on one wiki belongs to person x, and on another wiki to person y? My hunch is yes, as I believe total migration is still a work in progress, but please confirm. And if so, is there a way I can tell which user names on which wiki’s are post SUL and unified? Thanks, Erik Zachte
