I have enjoyed the challenges in the past and have found great inspiration there. Due to various reasons, my time and energy have been very curtailed of late and I have concentrated on commenting when I have been here. I hope that changes, but I don't see it in the immediate future. Perhaps you could try extending the challenge to two months so that those who are busier could get images in and raise the number each could enter to six for those that wanted to enter more images. Many thanks to you and your team for the great work you do.
