As visible on the above image of the "right panel" of the userecho welcome screen, some language translations may have too long strings implying:
- a placement of buttons not very beautiful (not on the same line, and overlapping the page)
- a part of the menu hidden outside the screen
I suggest the best way would be to use small icons instead of texts (like in "main panel" of the welcome screen).
- "Back" could be replaced with the usual icon : "<"
- "Sign in/Sign up" could be replaced by an icon like the outline of a person : like this
