Some time ago I linked to this site for people to see what Joseph Fielding Smith had to say about the "two-Cumorahs" theory. http://emp.byui.edu/marrottr/cumorah-jfes-dofs3.pdf
Now if you go there, you get an error:
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
But thanks to archive.org's wayback machine, you can still read Joseph Fielding Smith's statement:
For a while, people reported that BMAF.org, the owner of Book of Mormon Central, went offline. It is now back online. http://bmaf.org/about/mission_statement
You can once again see their corporate goals. Notice that (2) involves correlating with CofC scholars. The Reorganized Church of Jesus Christ of Latter-day Saints changed its name to Community of Christ (CofC).
It's fitting that Book of Mormon Central works with these scholars since they invented M2C in the first place.
Now, there are groups from both CofC and BOMC searching in southern Mexico for Cumorah.
Notice goal (3) also. Of course, they "help promote unity" by censoring any alternative views.
