Today I found a very interesting pool comps site (poolcomps.com). They seem to have a large number of both free to play online pool games as well as pay for play pool games.
I've sent the management an email to see if they are considering setting up accounts that will allow one pool player to refer another pool player and receive some form of compensation for it but haven't heard back from them yet. I'll let people here know if they decide to go ahead with this. The best advantage for referring a player is that a whole bunch of pool players and friends can easily get together to form their own community within a particular site. There are not enough online pool sites out there at the moment that have the ability to only see the players or friends that you want to see online.
UPDATE, Oct 2008 - At some stage in October 2008 Pool Comps ceased trading.
