I am looking for information on the Classes Plugin.

I am trying to setup a site similar to EduBlogs, for use by teachers within our school. I have got things setup for the most part, however, I can't find an option for anything resembling the My Classes portion of an upgraded Edublogs account. In looking through older forum posts it appears that this plugin was headed into beta about 2 years ago. But, I can't find anything written about it in the near future or an available plugin that would enable those features.

Please let me know how and where I can find this plugin.
