How do I clone maps?

I'm sorry if this is a noobish question, but how do I clone somebody else's custom map? I've made my own U.S. Civil War map, however, because of the map background that I used, and my slight incompetency at making straight lines, many have reccomended that I use Ezzatam's MEGA USA map as a background for my map. However, I do not want to simply make a scenario off of his map, as I would like to edit some country borders, add/delete/move cities, and redistribute the income of states to make it more period accurate. Unfortunately, when I look at his map with attempts to clone it, I am only given the options of making a map preset, and making a scenario off of it, although it does show me clones of the map that others made. Do I have to be made a collaborator for the map or something for me to be able to clone it?

Cloning option must be enabled by the map creator for other users to be able to clone it.

Well I saw that other people had made clones of the map. Perhaps he disabled it after the clones were made?

If you want to clone map of ezzatam ask he, and if you have luck he allows to clone during some minutes.
