I added a github project not to long ago.
Its suppose to be for bbPress users who want a different layout from there forum more like phpBB forums.
this will add phpbb style forum to your bbPress installation.
to be able to see your forums like phpbb,
- go into the forums section
- set up your forums and categories
- make sure the parent of the forums go into a specific category
- then the file should handle the rest
props of this file goes to BOB1NZ
decided to take also put the file on github.
