I just returned home from an eight day cruise last night. I sailed on the Carnival Spirit and met a friendly crew member whom I'd like to keep in touch with. His name is Siarhei and goes by Sergei. I believe he is from Russia. My sailing days were from February 12, 2006 through February 20, 2006. My destination was the Mexican Riviera. How may I be able to contact and write to him?
