[FYI] Identifying candidates for Gerrit CR+2 permissions
I've been wondering for a while  about a way to get a list of quite
active reviewers in Wikimedia Gerrit who have not +2'ed any proposed
changes in Gerrit, implying that these developers don't have +2
permissions  and could be candidates to receive +2 permissions.
On the left you can filter on a specific reviewer (hover over the name
and select the "+" magnifier icon). After enough patience you can see
on the right the code repositories in which they have been reviewing
proposed patches in the timeframe defined in the upper right corner.
