An interesting proposal!
Just a thought....rather than having a "free for all"....how about having the critique "panel"...consisting of the last years photography AOM's.

I think everyone here certainly respects those chosen for that award.

I know it might , in some cases, be difficult to get them to contribute...but.......

This is not intended to imply that other's have no right to critique....it is only intended to minimize outright flaming.....

In youth, we learn....with age, we understand.
