Subforums

Is it possible to create different levels of subforums?  See attached image... I would like to create other forum folders inside "Quilling Guilds - New & Info"

Sure, see example of nested forms at the shipments page (demo)

I am not sure I understand your response.  What I want is nested discussion forums.

For example

General Forum -> Sub Forum 1 -> Sub Forum A

Ohh, please sorry. I've thoght about nested forms (grids), not forums.

No, it's not possible out of the box. But you can customize the solutino to support it. Add a new "ParentForumId" property to \Nop.Core\Domain\Forums\Forum.cs. Then apply appropriate grouping logic (the same way as it's done for categories)
