Comment: Comments on articles in Forum

YACS implements the second option.

The best option is probably to trigger the Content Assistant, from the Control Panel.

Then select to create a forum. Type a title for it. Also type a title for sub-sections. And hit the button at the end of the form.

This assistant will automate the creation of three different sections, all based on the YABB layout (for articles and for sub-sections), featuring auto-publication of posts, etc.

Else you can do it manually. If you already have some sections, edit them, and expand the box for layout options. Select the yabb option for sub-sections and for articles.

Note that sub-sections can be grouped together in the main forum. Use the same content for the Family field of sub-sections that have to be grouped together, and that's it.
