Everyone is right!
Toss em in at 0 minutes and cool your brew at some point. Then transfer your brew to a fermenter at some point and pitch your yeast. That's about all there is to it.
How EXACTLY you choose to do it is completely and entirely up to YOU, and it's the right way however you choose. You can put them in a bag, or not. You can let them sit for several minutes before cooling, or not. You can partially cool and then let them sit for a while and finish cooling, or not. You can filter them out so they don't get into your fermenter, or not. You can let them go into the fermenter, or not. You will eventually find a process that you like and that works with your system, and the process you end up using will the the correct process for you and your system.
I'm beginning to think that flameout/0min/aromasteep additions might actually be a good thing in the fermenter to get a little extra umphh! from them, but I have yet to try it so we'll see.
