What is the difference between tan and tanto?

Can they be used interchangeably.

Are por qué no/ mejor no only used with vamos? Or are these phrases more commonly used for all commands (not just ir)? 

For the road signs, are they third person singular for affirmative commands, and third person plural for negative commands? Or are both singular and plural third person used equally for either negative or affirmative commands?

1) Why do you say “No tienen casa” and not “No tienen un casa”?   2) Is it “algunas” and not algunos because it agrees with personas?  3) Could you also say, La gente buscó ayuda de iglesias… as well as en iglesias?   This is the first time I did one of these exercises and I found it really helpful!

I noticed a few mistakes here in this lesson. In some areas, for the "tu", "ellas/ellos", and "nosotros/nosotras" forms of "acaber" there are double "ba" syllables. For example, there's "acababas" instead of "acabas", "acababan" instead of "acaban", and "acababamos" instead of "acabamos". I've double checked elsewhere to verify the correct spellings of these forms and nowhere else did I find the double "ba" syllables.
