To view all pins on one page, click here: http://goo.gl/maps/6lxQ
1: Log into your Google account (this is necessary).
2: Go here: http://maps.google.com/maps/ms?ie=UTF&msa=0&msid=217710768001213283190.0004ac9ffae6ae244e691
3: Click "Edit."
4. Click on the blue pin button, and then drop your pin.
5. Edit your info in the pin's pop-up detail bubble (not somewhere else): I'd use a non-specific location (e.g. No—I don't actually live on Jeld-Wen field), and include a link to your profile for PMing, rather than email, as to not encourage the spambots.The map is set for anyone to edit, and anyone with a link to see.
Also, please be careful not to drag and drop someone else's pin elsewhere—for some reason Google allows this even outside the edit mode.
Let me know if anything needs changing. All credit goes to Bryce, who thought to make this.
