I see that IL is considering a new flag. There’s a website where you can vote for the existing flag or a new one. I suppose anyone anywhere can vote. You can vote once a day on each different device you have access to. I’ll withhold my opinion of the new ones but am not particularly fond of the current one either as it looks like an emblem on a bedsheet. Here’s the link.
