About time that something like this appears and you have certainly done a good job! Another issue to consider is "False promises" Don't tell a youngster in a developing country that you will take him to your nice country for a visit when you return and then you are never seen again! Please abstain from any doubtful commitments! Sorry, but we had a couple of volunteers in the past and I felt the urge to share this! Your post is great! Congrats!
