I just submitted the new strings for Moodle Mobile 3.0.0.
You can find the strings to be translated in the component: local_moodlemobileapp version 2.6 (you only need to translate the strings for that version, no need to copy the strings in following ones).
Moodle Mobile 3.0.0 will be released at the end of the next week.
I have started translating strings for the Arabic language. However, the Arabic language maintainers did not respond. Their last access is one year ago. Actually, I have submitted stings translation and translation corrections for both Moodle and Moodle mobile. As there was no reply (some translations were submitted two weeks ago), I have sent a message to Koen Roggemans who is coordinating the translation sector, but still no reply till now.
I have to participate in Moodle and Moodle mobile translation and maintaining the Arabic language. Who should I contact regarding this?
