There are a few reasons why I think this months has proved popular, for me I was waiting for an outdoor mapping project, as right now that is all I have tried, and I want to discover my style for that before moving indoors or to more detailed projects.

The other thing I think is the indimidation factor. when it was just half a dozen big names entering, then I can understand people being nervous to enter, however once you had various rookies and others like myself entering, I would have thought that would make people think they could 'hide' with all the others and it became less daunting, hence you got a kind of snowball effect.

I think now you have such a large group this month, as long as you are careful and dont make next month overly esoteric then you should retain quite a lot of participants
