Hey, and welcome to the Jira Training Hub :)
Please watch this quick video first.
First, don't spam! Second, you can introduce yourself and let us/me know what your main struggle is or what you wanna do with Jira / Confluence / JSM :)
However, the best approach is to jump to the Classroom section at the top, where you can access all courses and other resources. Don't forget to check the calendar and add the Jira Live call session reminder to your calendar. Also, all replays will be live in the Classroom.
