If you discover something that you think is an error, please research it on your own first to confirm that it is an error. Yes, it might be faster for us to look into it since we've been doing this for a couple of years, but if it takes perhaps 5 minutes to resolve one submission, and you multiply that to include all of the emails we get, it puts an unfair burden on our time. We're still working on cleaning up the damage that software inflicts on text. And we've already sacrificed many thousands of hours on this project. We need to get to know our families again.
Here are the resources you might need to verify that you've found a problem. Obviously some typos are self-evident and don't need research, but most are not. Many are unusual, but not blatant. Anyway, here's where you can go to do your research:

Joseph Smith's personal bible

VOLUME 2 - THE NEW COVENANTS (New Testament, Book of Mormon)
