Okay, here's the deal. My client posts job ads to his website. Applicants can register in his page and choose what kind of jobs they're interested in. If new job ad (new node) includes same interest(s) than a user(applicant) has chosen, email should be sent automatically to the user(applicant).
I am building the site in Drupal 7 and tried to solve this with Rules. Problem is that I couldn't find a replacement pattern to scope all users, only current user was available. Email should be sent to all users who have the same interest(s) than in new job ad.
Could someone give some tips?
