My elog has this config for the author:

Option Author = Filled In Automatically
Preset Author = $Long_name
Locked Attributes = Author

This works as intended: when you submit a new entry, the author name is filled in automatically and cannot be changed.

However, when Alice wants to post a reply to an entry the Bruce has made, the preset author name does not say Alice, it says Bruce. I haven't been able to find out how to change this (other than make the author name editable). Even when Author isn't configured as as locked attribute, it still displays the original author's name.

How can I get this to work like I want/need to?
