locked Re: Preventing Reply to Group/Sender mixups AND quoted messages #bug
In my view this is not "just a UI" issue. It goes deeper. PM'ing is anWell here I'm going to agree with what you said, while disagreeing that it ought to be applied here.
I suspect that "PM" carries with it semantics (expectations) that are wholly different from what a "Send to Sender" means in Groups.io. That is part of why I object to that model being applied.
I think Brian mentioned that he would expect (and prefer) that a PM be a wholly separate thing: not carry in the subject line nor a quote from the original message. If that's what you're imagining then that's not Send to Sender and you are not solving the problem at hand: you're proposing something else entirely, something Mark has said he's thought about, a forum-like PM system.
The other key bit of semantics involves the word "Private". Brian may correct me, but I don't think a forum PM generally produces an email message carrying the replyer's email address. Send to Sender does - it really is an offlist message with far more in common with a group message than with a "PM" in the forum sense.
