... and then notice the greyed out button on the right "Private" andI agree that grey, which usually signifies a control that is not available (doesn't "click"), is a very poor choice for a button that is actually intended to be used.
I would prefer to have a button labelled "Reply to Sender" alongsideIt was once that way. The criticism was that it made it too easy for members to accidentally click the wrong one.
I realise this gives something of an issue with the BCC me option -It is IMO essential for private replies, as otherwise you have no copy of message you sent.
could it be shown anyway and ignored for Reply to Group.I don't see the harm in leaving it present and functional. A person whose subscription is Digest, Special Notice, or No Email might find it useful to have an emailed copy of their reply.
