Expanding existing courses, "possibly in a month or two"
In Luis' "Incubator Updates!" post today in the main forum ( http://www.duolingo.com/comment/1043526 ), he was asked about plans for expanding the current courses. He's previously confirmed that this will happen at some point, but the new information today is that it's in the works and could happen within the next few months.
I'm very anxious for this. Hopefully there will be some more details about expansion plans forthcoming.
