For all who want to learn moroccan arabic, I have found one yahoo group:
http://groups.yahoo.com/group/learn-moroccan-arabic/
You have to register if you want to read lessons and download dictionary.
The memebers of the group are native moroccan arabic speaker and others who
want to learn daarija. This is very good group for learning language, especially
because you can ask native speakers when ever you need help.
Under the files section, you can find good written and recorded lessons.
That`s all from me for now. If I find other good recourse for learning, I`ll let you know.
