If you want to make your course available in the events section go to the course details page (you can find the course by clicking the burger menu and going to My events) and click the visible to public box.
Make sure your centre details are searchable by going up to your profile picture in the top right of the screen and clicking the centre you wish to update from the drop-down menu.
Scroll to the bottom of the organisation details page and click edit.
On the next screen click the Visibility/Privacy Settings link at the bottom.
In the display settings, you will need to have Public set to on.
You may want to have the bottom four options set to off.
Your courses will now be searchable in the events section.
Please note that steps 2-6 will only need to be completed once per centre however, you will need to ensure that "Visible to Public" is checked on all courses you want to appear in the events section.
