Hello.
We have been working for supporting Urdu wikipedia for a while now. I would like to update you on our progress. Unfortunately this wiki had created a new challenge for us. When we try to pick random 20,000 revisions to be used for our machine learning classifiers we only get about 100 reverts which is no where near enough.
We are working towards addressing this problem at https://phabricator.wikimedia.org/T120999 to adress the problem. You can follow our .progress for Urdu Wikipedia at https://phabricator.wikimedia.org/T120173 as well
