I'm very humble in suggesting this since I'm the new kid on the block.

However, I think that the various techniques should be separated in more detailed cathegories before it's too late. I mean: now that the Forum is quite new, to move the few already existing topics to a new cathegory would be a breeze. But later, it will get more and more impossible by the day. I know a pair of extremely good forums made almost unusable as a reference by lack of classification, and that's a pity.
To have a specific cathegory for each technique would be perfect, in my opinion (I wouldnt' worry to have too many cathegories in the "processes" section: after all this Forum IS about alternative techniques, so most of the space should be given to them). As a second chance, it wouldn't be bad to at least group similar techniques together (bichromates, other non-silver processes, print-out silver processes, developed silver processes, etc).
Well, that was just a thought. But honestly, I really believe that this should be done until it's easy to do...

Don't worry if some cathegories will stay empty for a while: someone will post a topic, one of these days...
