Having a real physical location is the only requirement, I just wanted to make sure this place is not virtual. Ideally, it should have a sign or something, so other people can verify that it's a real place, but it's up to you.

Regarding flyers, feel free to send the PDF to igor@btcmap.org and I'll host your flyer on our server. It can be tagged as your website and it will be visible to all the users. You can change it with your real website if you decide to have one in the future
