JomSocial Integration / Support
JomSocial is a 3rd party community / social networking component by Azrul.com. The extension itself is a powerful platform for any Joomla site with a community, from extensive profile management, social interaction as seen on popular sites such as facebook (which can be integrated as well), to photo/video uploading and showcase facilitys, group creation and management and all what you would expect from a community extension.
K2 Content Extension
K2 is a content construction component (similar to CCK for those acquainted with Drupal), which lets you create custom content types (items) for your Joomla! website. With K2, you can transform your Joomla! website to a news site with author blogs, product catalogues, work portfolio, knowledge base, download/document manager, directory listing, event listing and more, all this bundled under one component.
Again, Affinity has styled support for this component to visually integrate the powerful component from JoomlaWorks.gr.
