Thanks and well done Sara. I hope your recovery is going well.
For your information, aswell as building in Salesforce, I also take Syrian Refugees and unemployed people, train them in Admin and Dev and place them into new careers. That is my sense of responsibility learned through my life.
Kind Regards
