Clubs let you build your own section of Marketocracy for you and your friends. Inside a club, you have your own forums and your own rankings. There are many reasons why you might benefit from creating a club, or participating in someone else's club. You could:

Meet and chat with other Marketocracy members in your geographic area (maybe you could even meet face-to-face once a month).
Compete with your friends or co-workers (make the guy down the hall prove he's the best investor in the office!)
Because while competing against 50,000 members can be fun, competing against your friends, family or coworkers can be even more fun.
If you are already a member of an investment club, you can use Marketocracy to make it easier to communicate between regular meetings and compare performance.
If you're a financial professional and would like to use clubs to keep track of and communicate with your clients or associates, you can contact us about creating a "private" club that won't show up in the list of clubs on the site.
