The Engineering Community team wants to measure the involvement of non-WMF code contributors looking at how many users with +2 permissions we have in Gerrit, and which is their affiliation.
Tables
* Full list of contributors who have exercised +2 OR -2 in Gerrit (name, primary affiliation, number of changes resolved) in the past month.
* Same as above for the past 12 months.
* Same as above for all time.
Graphs
* Month by month, total number of contributors who have exercised +2 OR -2 in the past three months / in the past 12 months / all time.
** X: months
** Y = number of contributors
** Three lines for current month, last 12 months, all times
** Tooltip shows the data for each month
* Month by month, percentage of contributors who have exercised +2 OR -2 in the past three months, by primary affiliation.
** X: months
** Y: percentage of each affiliation
** Percent stack chart showing the distribution of the 100%
** Tooltip shows the data for each month
