Well, yes and no. In the example above, the request was to provide a link to the original article from the rss feed.. not from the site itself.
To do what you are requesting is quite similar. Entries are displayed, in summary and detail, with the smarty file entries.tpl. Your template may have a custom version, but if not, it will use the file from /templates/default/.
Entry titles are often displayed with something like this:
Code: Select all
<h4 class="serendipity_title"><a href="{$entry.link}">{$entry.title}</a></h4>
You could change that to something like this:
Code: Select all
<h4 class="serendipity_title"><a href="{if $entry.properties.ep_aggregator_articleurl}{$entry.properties.ep_aggregator_articleurl}{else}{$entry.link}{/if}"</a></h4>
The above basically says "if this is an aggregated entry, the link to the entry is the original link, but if not, it is my site's regular entry link". Let me know if you require a more detailed explanation or if you can run with it from just this.
