Hello, Magioladitis, MARKELLOS and Wikimedians in Greece -- thank you for submitting this grant report and for clarifying the questions regarding the expense documentation that we sent by email. I have reviewed both that documentation and this report, and, with this, your grant for Wiki Loves E.U. is closed.
I think that, for the second edition of Wiki Loves E.U., reaching out to EU institutions to promote the contest might be helpful. In terms of planning, maybe a less ambitious project (for example, not intending to fly specific winners, etc) might promote sustainable growth in the initiative without requiring a big investment upfront that will only be used by few people.
We will apply the second underspend that arose after this report review to your Wiki Loves Monuments in Greece 2019 submission.
