How simple it is depends. I've been looking at this myself now that I'm aware of it. Between the heads tags is correct location based on Google documentation. I don't know if it can be placed anywhere else.Not sure if you can use external file but if you can you might want to look at feed.php for how you might implement as external file.
For the head tags In the template viewtopic_body.html is loop for the topics, you can try to use it in overall_header.html. Anywhere between the heads tags add:
Code: Select all
<!-- IF S_VIEWTOPIC-->
<!-- BEGIN postrow -->
{postrow.POST_AUTHOR_FULL}
<!-- END postrow -->
<!-- ENDIF -->
Purge the cache, you always need to purge the cache after template edit. Load a viewtopic page with your browser and view the source code, if it worked you should have list of post authors. If that does work you are most of the way there, most if not all the template variables are already available.
