The 7^th Conference of the International Water Association just took place in Warsaw and now it is time for packing up, enhance the network of contacts with new colleagues and do some rethinking considering the trends seen in this event. Over 100 people from all over the world met at the Centre for Innovation and Technology Transfer Management of the Warsaw University of Technology to discuss about odour management.

   The organization had less than a year to organize a conference. The decision about where to organize the IWA conference was taken during the last NOSE, so that left little time to organize things like calling a scientific committee, reviewing papers, sending them back to authors and asking for the versions corrected, booking a room, dinner, asking for chairs, etc. There is little to blame to the organizers taking into account the short notice time given to set up this event.

  There is just one month left for the II International Odor Management Conference and Technology Showcase (OMCTS) in Los Angeles, organized by the Canadian company Scentroid. The event will take place between the 1^st and 2^nd of November 2017 in the University of California, Los Angeles (UCLA).

   This is the second edition of the Odor Management Conference and Technology Showcase (OMCTS), organized by Scentroid. The previous edition took place in September 2015 in Toronto, Canada.
