Moodle Forums are a great place to start getting support from the community, share ideas and meet others in a community of your preferred language. Moodle forum are available for almost all major language communities.
Support requests for Competencies feature which was just added in Moodle 3.1 are posted in many different forums by the community members. So, Moodle HQ has created a separate forum for discussion about using competencies, competency frameworks and learning plans.
You can check out the existing threads in the Competencies forum here and post your queries about competencies, learning plans etc. in that.
Still not sure where to post your Moodle query, check out the list of all available language options here – https://moodle.org/course/
