The "Misc 2x3 View Cameras" section is extremely sparse, so if expanding it is what's intended by "MF view and technical cameras" then I think its an excellent idea.

Most of the books I've seen define large format as 2x3 and up. 6x9 format is all but dead in the MF world, but there's quite a number of 6x9 cameras being made by the LF manufacturers.

Its also obvious that there's a growing interest in 6x9 on this forum. I'm starting out with an old 2x3 Technica (although I'm also getting my feet wet with a 4x5 Crown Graphic). There's arguments pro and con about whether 6x9 is a good way to get started in LF photography, but the fact remains that for many beginners its an appealing transitional step. I've also seen numerous posts from professional LF photographers who use 6x9 exclusively. It belongs here.
