The mentorNET project team held their 3rd Trans-National Meeting in September 2020. The meeting was (at last) face to face in Stuttgart, Germany with only one partner needing to participate remotely. The meeting was hosted by ifa-Akademie at the Europa Zentrum in the city centre. Topics for discussion included the technologies for the MOOC mentoring course and the App that will form the focus to enable the development of sustainable networks. The meeting was held on 15th and 16th September 2020 and it really was great to be able to meet the team in person after many months of having to do everything remotely.
