I want to say "I have not written since December.  Is this the correct way to say that: Je n’écris pas depuis décembre.

I was marked wrong for writing "... car les activités y sont plus ..." in the fourth sentence.

Note that you use à when describing going to or being in a city.  And you use de to indicate being, coming or returning from a city. 

Does this mean that de can also be used to describe being IN a city? 

I also want to say how much I have learned in the short time I have become a subscriber to Kwiziq- " Votre site est excellent !"

Also, why can't I use 'demander des questions' instead of 'poser des questions'?
