There were some amazing shots posted in the last challenge, but I'd like to politely discourage everyone (if its ok) and ask maybe only photos taken for the challenge be posted, not some great old ones that fit the theme. Or maybe let everyone have one archive submission and one new.
Also, I think it could be great if people share maybe a couple small hints if it relates to the challenge. So for water, maybe we can talk about some of the things that make shots with water difficult and how to over come them. I guess I'd like to see the challenges as a way for people to improve more their skills or learn something new if possible, as well as take some new photos.
