Thank you very much for making a Spanish version! ¡Muchas gracias, de verdad!
If you want to improve it, I (a Spanish native) would use just "Nombre:" o "Nombre de usuario" instead of "Inscribe"; "Puntuaciones" instead of "Puntuaciónes", and "Acerca de" instead of "sobre", as it is its usual translation.
Keep up the good work! ¡Muchas gracias otra vez!
