Mindy,
1) How can you change the subject line of a rejected post? (so it
doesn't say "Your message was rejected" but something more gentle).
I wish you could. I could have sworn I'd requested it in beta, but maybe I've just thought of it so many times.
What I do as a work-around is use Send Message instead, and if appropriate just Delete the pending message.
The disadvantage is that it doesn't act as a Reply (that's a suggestion I've been intending to post in beta) so if you want to quote the member's post you have to copy it first, then click Send Message, paste it in the body, and mark it as a quote. A bit of a pain.
3) The daily digest on io is very short, I am getting several a day.
It says "up to 12 messages" but these have fewer messages in each (on
average 7).
Are you looking at the list at the top of the digest? That is a list of topic headings. If a topic has a number in parenthesis on it then it contains more than one message. Add those up, including the implicit (1) for topics with a single message.
If that doesn't equal 12, and if this isn't the last Digest you received that day for that group, then that would seem to be a bug to report to support.
Is there a way to set how many new messages it has?
No.
5) When a message is received, it shows as sent to the group, as well
as CC'ed to the group.
Odd, I'm not seeing that in my email client (Thunderbird) nor in Gmail's web interface. I'm not sure what's going on there.
