One thing to be clear about is that the LF Forum, which Tuan started and was ported to photo.net, is really a different thing from Tuan's LF page, largeformatphotography.info. I think the original suggestion was to collaborate with Tuan on his LF page, which has nothing to do with photo.net. As to the suggestion, I think that's entirely up to Tuan. He's maintaining the page quite well, and if he wants to solicit submissions, it is up to him as editor to do so.
