I'm still learning proper etiquette, and I'm not sure how to handle this.
Recently I gave an answer here, and a couple of people gave some extra information as comments to my answer. In order to make my answer more complete, I added their suggestions to it, and also included their username, like
Edit: (thanks to @username), because I thought it was the proper thing to do.
Today my answer was edited to remove those lines.
I understand that those lines do not contribute to the answer, so they "shouldn't" be there, but on the other hand, it would seem unfair to just add them to my answer without mentioning who helped, as it would seem like it's my sayings.
Should I not include these lines in the future? Should I include people's suggestions from comments if I think it will improve my answer?
Thanks a lot
