Here's a new thread for this, so the instructions are at the top. Be careful to follow the instructions carefully; a few people have renamed the map as themselves, or have ended up in the Pacific Ocean!
Okay, here we go:
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 to Bryce, who thought to make this.
bump with the info.
