Hi Jay, long time no see, hope everything is going well.
You are right, I need to add a token called configuredUsername or something like that, because at the moment that setting really doesn't do anything (i think).
Looking for this fix too!
We can't use the articles at the moment, because real names anywhere on the portal is a privacy issue. I tried to make a template with [USERNAME] but it does not show up. So I guess we'll have to make due without knowing who wrote the articles...
You will need to change the comment template, (comment.item.html), you would replace [AUTHORFULLNAME] to [AUTHORUSERNAME] if you wanted username for example.
I apologise for this, I'll be adding a [AUTHOR] tag soon that will key of the configured setting. (so you won't have to change templates)
