Hello,
This is just a quick test of whether a normal OSM user can have a normal changeset discussion with an MS Map Builder user, prompted by https://www.openstreetmap.org/way/1267674441 being linked from a comment at https://www.openstreetmap.org/user/Pieter%20Vander%20Vennet/diary/400992#comment56982 
Hopefully you'll see this comment and be able to reply by the same method!
Best Regards,
Andy
