While I do know some of you are going to stay around for a while, others are already back to your home country. Because many of you are using the university provided email, contact will be lost as soon as your account has expired.
You still can reach me on Facebook or Linkedin networks, and I think it is a good idea to keep the link on. Sometimes you may need a recommendation letter or discuss any technical issue. Other times I may ask for some traveling advice. Who knows.
So farewell and see you online.
