People can only see this map if they know the password, so please don't share the password with anyone!
To add yourself: Click "Additions" then click "add marker (simple)" or "add marker (detailed)". In both cases you can enter your address or click "map select location" and click on the map to drop your pin there. If you click "add marker (detailed)", there are tabs you can fill out with contact information, the simple version is just location and short description, it's up to you which you want to use.
You shouldn't list your exact address, a nearby cross street is perfectly fine.
