Goodbye, my friend [Editorial]

Presents the introductory editorial for this issue of the publication.In May 2015, our society lost a dear friend and a mentor: Frank Reyes. Frank was the Treasurer of our society. He would not miss one Administrative Committee (AdCom) meeting, always there to help everyone and to mentor the ´fresh´ AdCom members. He was a father to all AdCom members. Rest in peace, Frank, we will miss you! Frank, this issue is for you.
