Spanish language Q&A Forum

Hola! 

I'm having a hard time wrapping my mind around the purpose of doubling down on the indirect object usage in some of these examples:

"Ella le envió un regalo a Miguel. 

She sent a present to Miguel."

In this example, why do you need the le if you already have Miguel. It reads to me literally as "she him sent a present to Miguel" and I suppose it feels like excessive and unnecessary additional language in an already clear sentence. Is it for emphasis? Por favor ayúdame a entender.

In the example, 

El armario es dificil de montar, can you say (difícil a montar)?

Is that acceptable in any situation?

I continue to have exactly the same problem as the users below.  Your team really needs to fix this.

I believe that according to RAE, the vosotros form of both verbs should have a tilde – creáis.

This problem is in addition to the yo form problem others have mentioned.

It seems as if porque would convey the same idea and is probably more often used in conversation.  So is de tanto more formal, literary or is it used in the street?

Daba escalafríos andar por el pasillo. Is there no need for "me" or "nos" or are they optional? "Me daba escalafríos"?
