When you look at the Discussions page, the page displays the total number of replies to that discussion and the number of unread replies. In the screenshot below, the unread number is highlighted in red.
The unread number should only be highlighted in a color if the number isn't zero! (Or, as an alternative, the color for zero/non-zero could be different.)
As it is now, you have to look down the list closely to scan for numbers that aren't zero. The highlighting isn't useful to help you find unread messages.
Please change this so that only non-zero numbers are highlighted in the color OR use a different color for zero/non-zero.
