title: Embedding a foursquare map into web site + feature with check-ins
body: <p>My friends and I start a web/app studio, so we created our own web site.</p>
  
  <p>We have an idea to embed a foursquare map into web site, but it isn't all. A special feature: a map should display our last check-in(my friends and mine) for each user of site. We are four, so - always four check-ins on the map for each guest.</p>
  
  <p>How can we realize this feature?</p>
