The MSCA explained by your National Contact Points
GF 2016: I have noticed that the first page of the online application requires you to submit a short summary of the proposed research project. Once I have completed this field, will I be able to further update it at a later date? (I noticed that this possibility exists for the acronym of the project, but I wanted to make sure also for the summary before submitting it).
Normally the draft document may be updated any time before the final
submission. This should be valid for the summary as well. (Answer by REA)
