Hey guys,
I changed my blog post layout to show not only the lastModifiedDate but the creationDate aswell.
There are two problems: How can I display the full name of creator and modifier and not the username?
How can I cange the code to display to something like User created the entry on $CreationDate and modified it on $lastModDate ?
Cheers! 
//This is a part of my blog post layout code:
##parse ("/decorators/includes/page-metadata.vm")
#set ($Creator = $blog.getCreatorName())
#set ($CreationDate = $dateFormatter.formatDateTime( $blog.getCreationDate()))
#set ($lastModder = $blog.getLastModifierName())
#set ($lastModDate = $dateFormatter.formatDateTime( $blog.getLastModificationDate()))
<div class="page-metadata">
<ul>
<li class="page-metadata-modification-info"><b>$Creator</b> created the entry on <i>$CreationDate</i> </br> <b>$lastModder</b> edited it last on <i>$lastModDate</i></li>
</ul>
</div>
