The different days have the dat/time in different colors...

The choice to know if you've read a post is controlled by your browser (as others have said)

I use Mozilla's browser - to change such settings - I would go to Edit -> Preferences - then choose Appearance - then Colors - and there are choices there for visited, unvisited links...this is probably the same for firefox... (same authors)

I haven't a clue what the settings would be for microsoft internet explorer...but my version of IE does change the underlined color when I've visited a page...

Are you keeping history?
