Dear all,

there has been a large variety of online tools and meeting platforms throughout the lockdown, the COST office has shared a number of these tools for online meetings on its webpage, which you might find helpful  https://www.cost.eu/cost-actions/online-networking-tips/.
Hopefully, we will not need them and can continue to look forward to some face-to-face meetings  !
