Regularly visit the forum — I would recommend at least once a week, but preferably more often — and subscribe to notifications for the Announcements and Stable Updates categories.

Take a look around in our very elaborate Tutorials category, where you will find ample excellent advice, tips & tricks, and full-scale tutorials.
