I'm quite impressed with this proposal. At first I never thought a proposal about flags would make it this far. How are the users being attracted? What is the pre-existing community that was linked in the application form?
The "community" here was listed as https://reddit.com/r/vexillology
Now I don't know what Robert's past thoughts on existing community were, so I didn't close the proposal based on that, but that honestly doesn't look like a legitimate community for this proposal. From what I can tell, there is no discussion taking place about flags there. It looks like a forum where people can simply design and show off flags they've created. And from what I can tell, nobody in that Reddit has ever mentioned the proposal ongoing here.
I fully anticipate this proposal to be closed at the four month mark for not reaching the thresholds needed. It is going nowhere and does not have an interested community behind it.
