Until the bug gets fixed to change the color of messages that have been read, here's what I do to save time: When I've read the last message in a group, I go to the discussion forum, click on the last message, then go back to the discussion forum. The message has changed color. Next time I tune in, I start there.
The new rules make me edgy, not for me because I'd never dream of coloring outside the lines, but because some of my favorite posters may have trouble biting their tongues. So much happens with this stock that, for me, needs interpreting I'd hate to lose anybody. Particularly since I can discount the extremists and bickerers as required. Stay available!
