This also doesn't have the sort of language I'd expect from a project associated with the EU ('supported by', 'views do not necessarily reflect those of the EU', etc), which is what signaled to me that it wasn't official. Even calling it a 'community-led initiative' seems to me to risk misinterpretation, in potentially suggesting that it is some sort of EU initiative that is community-led, when it in fact appears to simply be a group of people and not associated with EU institutions at all. It does have a logo, however, which seems to be extremely important for EU-associated projects.
