I am trying to produce a link in a single Joomla article that indicates another article, but can't observe how do this?

Thanks

You are able to connect to it such as this:

index.php?option=com_content&view=article&id=ARTICLE_ID

Make existence easy on yourself and install JCE. The hyperlink function works much better and enables you available a listing of menu products, articles, as well as other extensions using the right plug ins. Very handy tool.

Better still than JCE (well, simpler and fewer to set up), is LinkR http://extensions.joomla.org/extensions/structure-a-navigation/content-links/4010
