Data exchange platform

It is a non-commercial project, a page that I've made for my student group while we were beginning our computer science studies. The platform is based on Joomla CMS, but is also integrated with other tools, like Google Calendar. Via the platform, students may upload materials, inform each other about important events, and share any other useful content. Another thing that differs this project from commercial ones, is that SEO (Search Engine Optimization) was done in reverse, i.e. the web page was made invisible to search engines, to get rid of most of random and unwanted traffic.
