pot limit omaha

Hey all, I've been wanting to learn Omaha for some time now. I read all the time about how profitable playing Omaha online can be due to the massive amounts of fish, but right now I'm one of those Omaha fish. Anyone have any good tips for starting out with Omaha? I already know the basic stuff like only draw to the nuts and so forth, but anyone have any good strategies/tips for game situations? Thanks for all replies.
