To join the map, click on the 'Add me' option that appears in the upper left hand corner. Alternately, you can add yourself by clicking on the "Hi! Please Add Yourself" link in the pin 'bubble' that appears over their pin on the Map itself.
Choose your pin color (we suggest PEA green!) and upload your PEAvatar or other picture.
If your pin isn't in the right place, you can put in your ZIP code to locate it correctly if in the US or you can use the "Edit Pin" function to move it.
