I actually did send a mail to my mentor regarding a few questions I had about the task three days ago... do I send a mail to the admin email ID given, or should I directly send in my CV and motivation email?
Yes, send your CV and motivation to the mentors directly. Do not expect mentors to answer during the weekends.
Is it too late for participating in Phase 1? @agheata
Newcomers, please start here
What is the status of the proposals that we had sent? Should we start working on proposals?
At this stage, many projects are still evaluating candidates, and some are very popular, so mentors are doing their best. In case they advised you to write a proposal already, they will probably give you feedback, just ask them.
