When will alpha testing for Arabic come out? I'm interested in learning Arabic.
Probably not for a while.
Estimated launch: 3/1/18
When the course will be close to be released (close to "beta" phase which is the name Duo gives to the first release to everyone).
And this will likely take months at least.
....if not years. H
By alpha do you mean stable? It is at zero percent so probably not for a while as OmegaGmaster said
