...as well as some additional posting requirements for that section. Not just numbering your photos, but perhaps listing settings used for the capture(to ensure a minimum level of homework done), an maybe a sentence or two giving an intent behind the image as well as self-critique.
That's required at several other forums I have visited.
That would be certainly requirement if we had a C&C subsection. The way I see it beginners only became the C&C area as a result of a choice to allow photos to be posted there since so many beginners would stick photos in there rather than in the galleries. It's a bit of a dividing point since on the one hand many beginner questions often directly relate to photos they've taken (even if their opening post has no photos many giving advise ask to see them); whilst on the other restricting photos in that section increases the moderator burden to shift them around into the right areas.
The thing is if we start to make critique more pro in the beginners section its giving a very heavy bias toward beginners to get critique. As a result intermediate and advanced level photographers are going to follow suit and the beginners area will increase in popularity as a place for people to simply put their C&C photos (because it will be where the critique is given and where proper posting for it is enforced).
