Great question. Not like we don't have over 100,000+ posts
Depends.
BBQ isn't a recipe book, so you can't follow just a step by step. At least that's the way I approach BBQ. I never give just a simple recipe and say here... I try to teach a little technique along the way. I think most people posting "recipes" have that. So you won't find them only in one place.
There is the one forum they mention above.
THEN
You need to pick a topic, say Brisket, and go into that forum. There are recipes buried in many threads, but not everything gets moved into the recipe sub-forum.
I leave all TOPIC specific threads in that area. If you want to become say a Brisket expert, live in that sub-forum and you'll be well on your way.
If there is a specific topic we can help you find, let us know.
