Group name is case sensitive so @Italia and @italia is different groups. 100% logical but tru fro intuitive point of view. Not sure how to fix. Again from intuitive point of view @italia and @italiA and @ItaIa should be same groups.But this is just my point
What do you mean? There is no way to create group "Italia" if there is already group called "italia". Username should auto-link in your case, I'll fix that. ‎- псы в рапиде
there is group italia so link is @italia but I could write link @Italia ‎- Все собаки попадают в рай
