Hi Uwe, thanks for checking up on me. I'm still in school and have been painfully busy this semester. So hello-ruboto is on haitus and I haven't looked at the Up button for some time now.
But I do plan to get back to working on this in the future and I will keep you posted as I do.
I'm also thinking about bumping the format of the tutorials to a github page on octopress both so that I can learn about github-pages / octopress, and so that the tutorials will be a little more friendly.
So when I next get a chance, I'll be revamping the tutorials, getting back to debugging this one, and then continuing on.
Thanks for all of your hard work making Ruboto possible!
