On svwp there has over the years been 45 individuals who have each made more then 38000 edits. Of these 45, 44 are still active, only one has left (in 2009) making 97,7 still around. For the users with less then 38 000 edits, only about 6 out of 10 is still active. Is this a global valid number, that when you have made 38000 edits you are fully addicted to Wikipedia ("until death do us part")? Anders
