Private Source Boxes (Remove Ability to Edit Other Peoples' Sources)
I use the source box a lot. The way I use it is that I create sources for different record collections, such as the 1891 England Census. Attached is a screenshot of my source box.
Since these are general record collections, they can be attached to hundreds of thousands of people. When I attach a source to an individual, I add a link in the Reason to Attach Source section to give more information. But, I don't change the URL of the source to the URL of an individual record. That changes the URL for EVERYBODY the source is attached to. Recently, my 1891 England Census source was changed to give more details of a George White, one of the many people the source is attached to. The 1891 England Census source is also attached to a William Gerrard, another of the many people the source is attached to who is totally unrelated to George White. Here is the newly edited source in William Gerrard's sources.
You can see how this presents a problem. By changing the source to provide more details for George White, every other person who has this source attached to them, which is over 500, will have inaccurate information about some random person.
Sources from the source box should not be editable by people other than the creator. If you have created the sources, you should not have to worry about them being changed by others. This change would help me out tremendously as I am someone who uses the source box constantly, so I hope that this change will be implemented.
