Hello Jeremy,
Correction, the locale manager is not Masha (the subject suggests to set up both locales but it is for Mari (Meadow)). This is the locale you want to have set up. Could you let me know if you have registered in Pontoon yet? I couldn't find you from the email address provided to me. Anyhow, it is set up in Pontoon and ready for localization. Once you start localizing, I can change your status there.
Thank you,
Peiying
