How to proceede issues

• Mario and Eli start collecting all the different
  material on a reference web site
• Keep high intercoordination weekly basis.
• Should we share the work in an optimal way like,
  in the exact definition of the hands on sessions
  for example, defining exercises, questions
  answers for students question is could we for
  example split like (indicatively, just as main
  responsibles- editors of the tutorial
  presentation/doc)
