Hello!

Why use subjuntivo vs indicativo in this sentence? 

Una vez que ustedes firmen, no hay marcha atrás. 

I can’t imagine using subjuntivo, or maybe I’m just thinking of it as a real factual warning vs something hypothetical that I can’t imagine in real situation. 

Let's forget about our problems and let's enjoy ourselves.

Olvidémonos de nuestros problemas y disfrutemos!

-monos ("s" dropped from mos before "nos" added) used for olvidar, 

but -mos (present subjunctive) used for disfrutar.  Rule?

What is the difference between hay and tiene? does this make sense? "tienes un carro"?

Why is ustedes used sometimes for singular subjects?

For example, Ustedes hacen una tarta de chocolate deliciosa. - is translated you make... It seems to me it should be: Usted hago una tarta de chocolate deliciosa.

What am I missing?

Hello! Unless I am missing something, I was provided a question in the drop-down where I had to pick the correct conjugation of tener with the imperfect subj. It seems to be that both tuviera and tuvieses should be accepted, however only "tuviera" was. If tuvieses is not accepted, it should not be listed in the drop down. Perhaps you can fix this? Gracias.

Couldn't you also express the last sentence like this?:

Será un día estupendo!

Can this also be translated as:  Va (usted) a salir a comprar pan esta mañana?  If not why not?

I don't understand why instead you'd use:  Usted sale a comprar pan esta mañana?

Thanks, Lia
