When I read a post it turns from blue to purple,
this makes it easy to go back and know which are new posts to read. Very useful. Yet this function seems to disappear periodically and all the previously read
posts turn blue again. Frustrating! Then I can't check back old posts and see if anyone new has weighed in.
What's the low-down on this?
