GaussianNoise - Thanks mate. If there's one thing I am, it's stubborn!
AndyK - As many as you wish to post (in colour or B&W). It's not a competition. The Challenge is to shoot the chosen theme in a way that satisfies YOU (which could be a single shot, a few shots, a panel, or something else). I look forward to seeing your contribution.
Tony - No worries! The deadlines are just to give us a little focus (no pun intended!). As long as it gets us out, shooting, trying new things and above all ENJOYING IT, then the Challenge is fulfilling its brief.
