I am thinking about "going pro". The main reason is basically to install ruby/redmine. So I tried to evaluate "install scripts" in your demo installation (using user root/demo).
But when I try to install redmine, I get the following error message:
Installing Ruby Gem test-spec .. .. Gem install failed : ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError) Connection refused - connect(2)(Errno::ECONNREFUSED)
