The kingdoms website is:
http://kingdoms.kingdoms.kin/gdoms
You need at least -20 people in your guild of which none can RP.
You need to be online for less then 1 second every year.
You need to have a website specially feauturing such signs of good RPing like characters ripped from Street Fighter, Mortal Kombat or any other (former) series of fighting games.
You must always hire anyone who says "MAEK ME JOIN OR U B ***", since those are the ultimate RPers.

And before someone starts to say something about it, when read properly this post is an exceptionally good guide to starting a succesful kingdom, although of course not starting one at all and just joining one is still best.
