Dear Miss Snark:
First of all, thank you so much for this blog! It's an absolute gem and I have become completely addicted (I only discovered it fairly recently, and am now working my way through the archives).
To the point: I'm a member of a very good critique group. We all look at/comment on each other's manuscripts. That is, after all, the point, and is also one of the reasons I actually managed to produce something good enough to get an agent interested in the first place. I don't want to leave the group if (when, I hope) my novel is published; it is an immensely valuable resource for me, not to mention part of my social life, and I would certainly plan to run future novel drafts past the group for critiquing.
What is the Honourable Miss Snark's view on this situation in the light of possible litigation, accusations of stolen ideas etc? I should point out I am writing from the UK, where we don't generally sue as much, but still...I should like to hear your thoughts.
Generally it's not the people you know who are going to be litigous loons, it's the whack jobs who show up out of the blue with a conviction that your purpose on earth is to help them. Generally those people get weeded out of a critique group or the group folds.
It sounds like your group is rolling along nicely. I wouldn't worry.
