1. From your wordpress dashboard, go to forum – manage forums
2. Create new forum
3. You can create your own group if you don’t have one, and set permission, see example in my screenshot for permission setting.
4. Enter your forum name, sequence, and description.
You can later create topics and posts inside this individual forum.

Sequence: I suggest you have by 10 or by 5 interval, so later on, if you decide to add new forum in between, you don’t have to adjust throughout everyone.

5. Start posting on the forum front end and grow your community.
