In this video, I'll demonstrate adding a new place, in our example the new place is the Colosseum, in Rome, Italy.

Please notice that you can always make use of other sites such as Wikimapia and Wikipedia to check the places' spelling, addresses, etc.
Also make sure to add as much info as you can about the place, and if it has different spellings try to write them all.
Finally, some places have branches all over the world, and some other places are not very well known and people may not know where there are from their name, so it's always better to write their names as follows, "McDonald's Westford" instead of just "McDonald's"
