i would opt that you make a own part besides the Lounge for medium format cameras, that are to be used like LF cameras, but have 6x9 backs, like technika and technikardan.

This cameras will often serve as starting drugs for LF, and when you bury this topics in the strange lounge mix where nobody finds it you miss chances for promoting LF...

Big disadvantage of the lounge is that is is not showed to non-members. So you maybe miss the people that start with technical cameras in 6x9 because of the film they are used to, not sheet film.

For these baby technical cams there is no home in the internet.. in apug they are buried among the Hasselblads and rolleis, and here they are into "non-photo-topic...

if you start with such cameras, you have the knowledge for this cameras here, and nowhere else, and you miss a chance for new forum members...b especially because the lounge is hidden to visitors...
