When you add, delete, or edit information or sources, it is very helpful to other collaborators to know what you did. WikiTree is all about collaborating on our one family tree. A short explanation may prevent another collaborator from reversing the change you made. Though others can read the details of what you changed by clicking on the Changes tab in the profile, it may not always be clear why you made the change. I will admit that I do not always add an explanation (nobody is perfect!), but I try to remember to do this.
Here are a few of my own examples:
I just removed several good sources (birth, marriage, death, census) from a profile. That’s what it shows on the Changes tab, so you can understand how someone could think “Star really lost her mind this time!” and add those primary sources back into the profile. In the explanation, I wrote that I moved sources that belonged to his father-in-law to the correct profile, hoping to alleviate any concern someone might have.
When I change a birth or death date, I write “changed birth date & added source for birth” to explain that I added a source for the change I made. I try not to change birth and death dates and places without citing a source because I might have wasted my time if another collaborator reverses the change because my reason was not clear.
I write “changed state name to colony name” to alert a reviewer that the date of the event required the change, not a new source. Maybe my note will remind others that Pennsylvania was not always in the United States and make them more aware of correctly listing locations based on dates of events.
Another helpful WikiTree member edited the county of birth for one of my family profiles and explained “county didn’t exist.” When I read this helpful note, I added more information to the biography, stating that he was born in Northampton County (now Monroe County), Pennsylvania. I also looked up when that county was formed and edited other family member profiles where someone was born or died prior to the date that county was formed.
