@inthehands Um, yes, but also no. Commit messages are memory aids, and the more they're asked to do beyond that scope, the less useful they are. So, the level where you add in team members is to recognize that team members might sometimes ask you questions like, "do you remember that bug you fixed? How did you do that? Because I think this situation is similar"
If the author isn't around to ask, the commit messages aren't going to fill that gap.
