Hi Alfiya :) Thank you for looking after the OSM data in Greece :)

I noticed that you added the transliterated names of some streets in Greece. You could consider adding the transliterated names as "int_name", instead of "name:en". That is the current consensus of the Greek OpenStreetMap community, and you can read about it at https://wiki.openstreetmap.org/wiki/Greece#Names If you have any questions, feel free to send a message to me or to the forum for Greece at https://community.openstreetmap.org/c/communities/gr/68 

Many thanks again for contributing to OpenStreetMap and happy mapping :)
