"How do I add the breaks I have surfed to my map?" is a question we sometimes get. It's pretty simple really - start by going to the All Breaks page and use the map to find all of the breaks currently listed on IST. Just zoom in on the map, click the red marker, and an info bubble will pop up. Just click the "I Surfed Here!" button:
That break will now be added to your map on your profile page, and you will be redirected to the break's page so that you can see what's going on there, post comments, photos, and videos, and start discussions related to that break. You earn karma points for adding breaks, but please don't spam breaks you haven't surfed at - that's a surefire way to get dropped in on, or even blackballed.
There are other ways to locate breaks on the site, such as going to "Breaks" in the main menu or clicking on a break's icon anywhere it's listed in a comment stream, sidebar module, etc. Click around and check it for yourself.
