I was wondering.

It looks like most users don't specify a location (eg. US, DK, etc ). I suggest using the location specified on the devices(s) installed. Every windows installed has specific location info about the user.

Another idea to get people to select a location could be to prompt the user if he/she has not selected a location. That prompting could be done when the user logs in on the website.

Thanks for a great initiative. I am looking forward to seeing the new projects coming up.
