Hello and welcome to the community,
I can create this for you, but I would need at least a couple of people who commit to moderate the category (to follow Mozilla’s participation guidelines) and their usernames here.
Also I’ve noticed that Ukrainian just has 5K sentences, and 17 hours validated. This means you are already recording repetitions, can you please check with the community to get a few technical people to help get the wikipedia extraction done following this process?
Thanks for your contributions!
