I installed Git and started using it without creating a config file. I noticed that PyCharm supplied my network password in lieu of the email address for both the Author and Committer fields.
Adding a config file solved that problem. When identifying the user and email, it picks up on that instead.
Now, if anyone can tell me how to edit a Git commit object, I would appreciate the info.
This happened again when starting another project. It seems that the config file should be created automatically. Defaulting to a password as contact information doesn't make sense.
