Just wondering if a new have you tried theme could be something for consideration.
After seeing the back focus button thread and not heard of it before and it got me thinking about all the other operations on my camera I haven't even begun to look at and thought a topic for the week to explain and for others to try and then post their examples and ask questions could help increase less experienced member interaction as well as those who are more experienced but just haven't gone there yet.
Could this be something worth trying?
