During these days you might encounter problems with the EasyChair system. The managers of the system have planned a system upgrade, that will take place probably on Thursday, April 16th. This upgrade will result in a few hours of the system being unavailable. So, if you encounter any problem with submitting your abstract or your paper, please try again a few hours later.
In any case, please report any problem to Ioannis Refanidis, at firstname.lastname@example.org .
Sorry for any inconvenience,
