Please accept my apology if this question is either a) in the wrong forum or b) already answered somewhere else on the forums (I searched but couldn't find anything).
My question is difficult to put into words as I'm not too familiar with xenForo's terminology, so I'd like to refer to a forum as an example of what I'm looking to do: godlikeproductions.com - please excuse the vile cesspool of human filth demonstrated throughout this forum. It was the only example I could find.
I'm starting a new forum and don't want a category and forum structure, just one main forum. Over time I do plan on organizing the forum into categories and forums but in the beginning I'd like only one main forum and 15-20 threads displayed on the main page.
Thanks in advance for any help received.
