We create a new badge for our users,and we want interaction with them when they get this badge, we think it will be more fun.
1.Can I send message to who get the specific badge at once?
2.Can system send them a message when they get the specific badge automatically?
Just like when people get Trust Level 1, system will send them badges.basic_user.long_description.
Thanks for helping. 
على وجه التحديد، “إرسال رسائل خاصة” مع مشغل “منح المستخدم شارة”.
