Please note: Due to the ongoing COVID-19 crisis, WCSP currently has a much reduced staff and resources. So it may take longer for new publication to be incorporated and we would ask you to refrain from sending feedback at this time and only to send it when we return to full capacity which will not be before the 1st of August 2020.
