I have invited previous translators from previous Transifex project but they didn’t join in yet
There are also 29 languages with translators but I would recommend actual proofreaders (top level on each team) to invite more translators (there are more then 54 000 words to translate).
Maybe you could share the project’s URL in your social networks and invite people: https://crowdin.com/project/suitecrmtranslations
Note: Translators can’t override Proofreader’s translations
