Dear ToniE
Thank you so much for your message.
The source of my information are my journeys. I'm tur leader, travel specialist in Memories Vacations bureau and travel designer (www.projektowaniepodrozy.com). I'm travelling a lot. From 9th - 22nd March I was on Cuba and saw these all places. Most of are tourist attractions. In deed, Benito Juarez had a house on Cuba. I didn't know about it before, but I've read about it on a board at the entrance wall.
So, you think when I will mark many places in different areas I will be no-realible for other users? I have so many information, places, etc, which I would like to shere with others.
What does mean that "that all data entered in OSM must be copy-right free". Is there in OSM place where i should mark, that is copy-rights free?
Regards,
Lucas
