Web Reporting is not part of the Community Edition.
We tend to adopt a policy making our product free for universities and other education institutions (as well as ONG). We can send you an evaluation license. However, I’m not sure what you ‘learning’ expectation are and if they are going to be fullfilled. All Reporting tools are different (no standard like MDX/XMLA). So learning one, is not going to bring you very much more than being an expert on this tool.
