ehm - nope - I still cannot get into the rules.
I can look at the page guide but not the rules page.
I think this might be useful to be able to do this as new people might want to have a quick look to see what the game is about before joining a league.
Look at the very bottom of this page on the browser (I think).
Along the bottom is
Next race - (in my case it as Malaysian 8h 53m 18s atm) - 247 managers online - Friends - ? Page Guide (the ? is in a big blue circle)
Click on ?Page Guide and it should open a window giving you information about the page you are looking at.
If you cannot see any of this then something is wrong and should be reported - maybe something to do with your browser.
If there is someone you want as a 'friend' ie someone you actually know or someone you converse with ingame then adding them to the list is just a shortcut to sending them a personal message or finding out how they are doing ingame.
I don't use it much
But lots of other people do as a quick way to keep in touch.
Click on a managers name (eg in the hall of fame) and then click on the button 'add as friend'
