It's under the main photography heading.
Re: Poppy's entry, I didn't see this picture so I don't know if it broke any rules, which state:
"Photographs may be enhanced using image editing programs, but remember this is a photography competition, not an image manipulation exercise".
Re: Dave, I don't know who deleted your picture, I think it was oversize although it was submitted before the rules were finalized.
It would be a good idea for mods to pm entrants asking them to rectify the problem before deleting an image.
Hope this helps.
