Earlier quoted context omitted.
I have found it's important when emailing/texting in Spanish to put the tilde in 'año', when I normally wouldn't bother with an American keyboard.
US-Based native Spanish speaker here. Very important indeed, specially when asking someone their age :) Whenever the ñ is not available (foreign keyboards, mobile, etc...), a decent substitute is "anyo", which is phonetically equivalent and also happens to be the Ladino variant of the word.
Agno is safer (same idea as in 'gnu'). "Anyo" is close phonetically to "anillo", that is a ring, but also a common source of jokes about little Frodo's sexuallity.
