Things I would like to see might be ...
Photoshop tips. No, not the drek you see on other sites on how to cook-book this fake look and that fake look, but exchanging tips between film/hybrid users. (No, I don't wanna just run somebody's action, I want to know what to do and why.)
Scanning tips. Hardcore exchange of ideas from people who really know what they are talking about. I'm still climbing the learning curve on this, and I'm sure others are as well. I get so {expletive}-ing frustrated at that other site where just about every question about scanning is answered with a chorus of "get Vuescan" as if it's the universal hammer for all that looks like a nail.

I swear if I posted that my car would not start, somebody would tell me to get Vuescan!
Printing. I'm sure there are others like me who shoot film, scan it or have it scanned, do a little P'shopping, then print on a commonly-available printer using over the counter paper and get prints they are happy to show off (as well as several that get ash-canned I'm sure). I'm looking for a new (larger) printer, maybe some discussion on which one to get, assuming that I don't have the budget of one of the EU nations.
Things like that. I think the site has a lot of potential, but it just needs to get started.
Oh well, you asked.
