Nazis have a way of trying to rewrite your story. They tell you how they would have written it and never seem to get around to how you could improve the story the way you did it. The twilight zone. Not always apparent right away, you generally know you've entered the 'zone' when the first person reads or as late as the first remark. Depending on your wavelength, a writing collective may simply think entirely different.
Most groups tend to govern themselves along the leader's guidelines.
How strictly they enforce point of view, passive voice, action and story, etc. This can be even tougher if you don't even know what some of those things are. A group may be excellent, but only for certain kinds of writing. Science fiction and fantasy writers sometimes have trouble meshing because of intolerance or pre-judgement. Depending on the leader, the 'zone' could possibly become a safe haven, but only after you and they make certain adjustments.
