The one thing about a Web site, it always changes! Joomla! makes it easy to add Articles, content, images, videos, and more. Site administrators can edit and manage content 'in-context' by clicking the 'Edit' link. Webmasters can also edit content through a graphical Control Panel that gives you complete control over your site.

This is now implemented by inserting a Read more... tag (the button is located below the editor area) a dotted line appears in the edited text showing the split location for the Read more.... A new Plugin takes care of the rest.

It is worth mentioning that this does not have a negative effect on migrated data from older sites. The new implementation is fully backward compatible.
