add a field to registeration to subscribe to newsletter module I want something like the enewsletter module (it is for Drupal 6) for Drupal 7. 

I used simplenews module, it add a subscribing field to user registration and it is well, but my problem is that in registration user select with category(from favourites taxonomy) want to be subscribe, and in creating simplenews content type select the term that this email send to them,( send simplenews content type according to taxonomy terms ).

I found simplenews terms module but it is for Drupal 6.  

I try newsletters module but it is very complex and doesn't provide something I want.
in /admin/config/services/simplenews/add add multiple category you want,
by adding any category here, add term to newsletter category and you can do any thing with its taxonomy
