Hey Rabbit .. and USCoralSea,
Thanks for your comments!
I didn't answer about the little green circle yesterday, because -- quite frankly -- I didn't know the answer. Perhaps we should have had a contest to see who could figure it out first?
Today, in looking at the message index, I surmise that the green circle indicates a new topic. Does that seem right?
Best to all, and to all a great weekend!
Mike
