For the first edition of the Foundation's new quarterly report (2014/15 Q2, due to be published on February 15), we are still going to use the old active editor definitioin (per discussion with Toby)- i.e. we need the total active editor numbers for October, November and December 2014.
Currently December is still missing at [1] and [2] and I don't recall what the monthly update schedule is. Would it be be possible to provide this until next week, say February 12? It would be good to leave some extra room in case T87738 unearths any existing data quality issues.
