Dear ETHSA inaugural course participants,
Congratulations for making it into our private group space, after all the technical hassles! Once we all are a part of it, I hope that we will utilize this space to the maximum for adding content, starting discussions, giving and getting support from/to each other and following on each others' work.
Ato and Golda !
