The submission service is now open for both the European Fellowship and Global Fellowship strands of the 2014 MSCA Individual Fellowships call (call deadline 11 September 2014), meaning that applicants can create a profile for their proposal on the Participant Portal and download the application documents. The research mentor and fellow will need to work on the application together, and both should be included when setting up the online proposal in the ECAS submission system. Call details and documents (including an FAQ) can be found on the H2020 Participant.
