This is just an idea, but i would love to see almost like a 'lessons' section. Users can post a neat pic, and also post every setting they had their camera on. Such as quick shots of water drops, or night shots of the streets using slower shutter speeds, etc. Leave step-by-step instructions.. including what lense was used, filters, etc. You could also include photoshop steps if they were used to improve the picture.
Thanks,
Shane
