Hi, please create an OTRS language mailing list in Arabic (OTRS-AR). So it's gonna be a link like https://lists.wikimedia.org/mailman/listinfo/otrs-ar
For access : Who gets access? Volunteers with accounts with access to the info-ar queues (plus Foundation employees and other exceptional circumstances, at the discretion of the list administrators).
See the page : https://otrs-wiki.wikimedia.org/wiki/Help:Mailing_lists
