I'd rather leave the how to's as separate threads just so people can contribute their experiments to it. So you'd end up with say the DoF How To and it'll have loads of shots of people practicing DoF shots in it.

Yeah, all you'd have to do is use the table like I'd done, and directly link them to the thread, for example if the thread ends up on page 13 of the Photography forum, the person trying to find it gets to it with ease, it's still its own thread just much quicker to use
