When you set a comment's author in the CommentShowing event handler, this information will be exported, but not shown. Unfortunately, in its current implementation RadRichTextBox doesn't fully support the author and date created comment fields and this is why this information cannot be visible.
However, I've created a feedback item
, which is related to the corresponding item in our backlog, so you can track its progress and be notified about changes. I can assure you we will do our best to make this feature available in RadRichTextBox as soon as possible, but I cannot commit to a specific time frame when exactly this will be done.
