Click on the right-side menu item "Edit Trip Details". Make sure you fill you the second tab called "Trip Details". For best results fill out as much of your profile as possible. Include whether or not you're willing to carpool with kids, whether you are willing to drive, or anything else that will help others find you.
Editing your profile and trip details:
Click on the right-side menu item "Edit Trip Details". Make sure you fill you the second tab called "Trip Details". You do not have to do anything in the first tab (the map).This tab has the map, and two buttons with coordinates. The button "Fetch from address" will take the new information from the "Trip Details" tab. The button "Fetch from location" will take the approximate data from your browser (ex. city centre). When you move the markers in this tab, the markers will display like that on the main map. However, the search will pull information from the "Departure" and "Destination" fields.
