I found a few more who just had Budapest as location. You can manually create a Hungary List post once you have a few people to include. Keep an eye on people doing introduction posts or check on tags that they may use.

I think @pennsif did the original Brit List manually, but I decided it would make life easier to automate it. I could not check all those accounts for activity otherwise.
