Before I elaborate what I have been learning for contributing in translating WordPress, first, I need to explain that I am not the one who translate WordPress as a whole. Translating WordPress is a collective effort from many contributors who have been spending their time with high dedication to translate word by word in the WordPress core. Some contributors were working individually, other else were bonding and working collaboratively in polyglot (poliglot in Bahasa Indonesia) team of WordPress Indonesia Community. I participated as a poliglot team contributor. I invite you to join the team. Visit this link to get started.
