Found a cool site to keep track of high stakes games: http://www.highstakes.nu
For example: http://www.highstakes.nu/forum/Topic11027-2-1.aspx
-> Erik123 loans $200k from Sbrugby to play Phil Ivey, and Ivey vouched to pay sbrugby back should Erik go broke (which he did)
You can also insert a player's name and look up the big pots they played etc.
