http://en.wikipedia.org/wiki/Pot_Limit_Omaha
If we could get a few people here to make a little hobby out of improving this article, it could perhaps marginally help the popularity of the game. If you have ideas on how to improve it but are too lazy to go there and edit the page yourself, post them here and I or someone else might get around to it. I'd say the first goal should be to have enough content on Pot Limit Omaha specifically for it to break off on its own.
