The plan is to post an image every day. Removing the need for words. For chatter that maybe isn’t needed, but you write because you think you should post.
I doubt I will be able to keep quiet for a whole month, and since there are no real rules, just to post an image a day, I thought it might just be a nice kick in the bum for my shuttercal 365.
