Now you can find members near you and help people find you. For
your safety don't use your actual home address - the city will
usually be fine.
It's your map - add whatever you like. Want a map like this just
for yourself or just for your group - check out Atlas
or you can have
me set it up for you. Finally, it's not necessary to actually use
your real email address when the map service (atlas) asks for it.
They rarely check.
