I think I'm a bit slow, (must be the hormones), but what do the coloured icons mean in the first column of this site...e.g. the star...and how do you know this?

Hi Ram,
if you look to the left of the screen (your left) you will see some headings (above the statistics) one of these headings is icon legend - just click on this and it explains what they all mean.
have fun exploring this site - just click on different things and you will slowly learn how it all works.
good luck
