BLF Members Map
A map of approximate locations of BLF members.
Feel free to add your location:
Use the search box to locate your city, state, and country.
On the marker that appears, you’ll see a link that says ’Save to maps‘ within the bubble.
Click the link and select the ‘BLF Members’.
Optional steps for advanced users:
4. Click ‘View map’
5. Click ‘Edit’
6. Select the pushpin (added in step 2&3)
7. Edit ‘Title’ & ‘Description’ to include your user name and city, state & country (for example ‘the - Helsinki, Finland’)
8. Click ‘Done’
I expected more, but there's only 1 member listed from latin america, and 1 more from Spain. Maybe there's not as much crossover between blf and fotolinternas as I thought.
