If you are a fellow photographer, don't miss out on Metro Photo Challenge 2010. This year the three categories are "Emotions", "Favourite spot", and "Everyday travel". You are allowed to post three photos in each category. The challenge is free, and there are some really nice prizes to win.
Of course, I will compete this year 
. Last year wasn't a big success, but it's pretty easy to join the competition and you learn a lot from it. And don't be disappointed if you don't win – the winning photos are usually of pretty high quality.
