Edit templates:
"vbcms_content_article_preview"
"vbcms_content_article_page"

Look for similar code...

Template: vbcms_content_article_preview

	<vb:if condition="$showuser">
		{vb:rawphrase by_x_nolink, {vb:raw memberaction_dropdown}}
	</vb:if>

I have no idea what you want to change it to... so I leave that to you

You could just change the phrase, but you would be left with the ",".

Note: The phrase is already in a conditional $showuser, most people just use the CMS option already there. You would only need this if you wanted to customize the area.

Have Fun
