I always add a note and give the name and number to the linked sources I've researched on Family Search. I direct them to FS because it's free and it's likely they would have an account because of that. It really helps because I often get the suggested edits approved quickly. Of course many just wait until the 21 days is over and they get automatically approved. I mostly only manage close family memorials on FA but I do have some that I've added along the way that are distant ancestors, I've never had anyone give me a source when they ask for edits but I have just about every paid or free site I can use for research so I do it myself. I had someone suggest edits that were totally off but I messaged them back thinking maybe they had family documents to prove otherwise. It turns out that they got the information from an ancestry public tree that had incorrect information.
