This site showcases many of the capabilities on Plone as a intranet portal and community networking platform. Unfortunately, access to the bulk of the site is restricted to students, so I’ll just have to describe some of the things going on behind the scenes.
The design and layout of the site is done in vanilla HTML/CSS and integrated with Plone using deliverance, a python-based tool designed to facilitate theming and integration of web applications. Theming Plone has historically been somewhat challenging, but deliverance is a game-changing tool that revolutionizes theme development. It also provides to capability to integrate different platforms in a seamless way.
The site features a rotating carousel highlighting important content. Superfish, a jQuery-based dropdown menu system, makes it easy to navigate the content in the site. A helpdesk system, Zendesk, is integrated into the theme, allowing the students easy access to support staff. A number of other useful plugins are installed to facilitate the generation of forms and surveys as well as a discussion board.
The aspect that I spent the most time on, and has become a core product in several other sites as well, is a community social networking area. Each student has a profile and can post content to their own blog/wall. The students can tag their content in various ways that allows it to be aggregated in other areas of the site using Plone’s most powerful content type system.
