Thanks for offering to write the article. I'll be looking forward to it, and I'm sure others will as well.
Right now there are three sticky threads in this forum (B&W: Film, Paper, Chemistry), which is the largest forum on APUG. We haven't really created that many of them, and we're trying to be careful about creating new ones. We have been merging some redundant threads, but we don't make all of them sticky. If there get to be too many (like a whole page of stickies at the top of one forum), we'll think about how to fix that, but at the moment, that doesn't seem like it will happen in the very near future. It will probably make sense at some point to split up "B&W: Film, Paper, Chemistry" into two forums (B&W Film and Processing, B&W Printing Papers and Chemistry, or something along those lines), but for now, Sean's got other things to work on.
