Akeeba has the best extensions and this subscription component is no exception. In addition to the documentation, Nicholas also answers you on the forum within minutes usually and his answers are 5-10 paragraphs long in detail. He actually tries to think things through with you and suggest a better way to accomplish what you are doing.
The subscription component is powerful and works great. It also comes with a million plugins all well documented.
Professional products and support - too amazing for one guy. These types of extensions are what make Joomla so powerful and special. Thanks!
Like other multi-lingual extensions, it's a snap to use the language manager to override any language string used in this plugin.
Thanks for the great review!
