Congratulations SULA! Do you know where in Mali you will be? I hope you enjoy the work, its sounds very interesting what you will be doing. I'm not sure how well Mali is connected to the net, but I'm sure we will eventually get to see some of your cool pictures.
You will be perfect for the job. I'm sure it seemed like a long, anxious process, but the rewarding experience will be infinite. We all wish you the best.
