Rumor has it that Joomla! 1.6 will have customizable access levels. Until then, however, the only way to customize access to your site is via third party extensions or hacking Joomla! yourself. The popular third party extensions (which shall here remain nameless) tend to be commercial, charging a fee or subscription for the latest and greatest version, and requiring registration even for the unsupported or semi-supported old versions. If you haven't used them before, you can't be sure of how well they'll integrate with the rest of Joomla! This is obviously not an ideal solution, especially for the webmaster on a budget. Following are instructions for hacking Joomla! yourself to add an extra user level called "Subscriber" who can be given access, for example, to premium paid content. These steps were carried out successfully on a Joomla! 1.5.10 installation, but there are no guarantees, as the author is not a Joomla! developer; try at your own risk!
