I made a little mini-game that users can spend their money on (if enabled). It's a fairly good way to get some excess gold out of the economy.

Added a little micro-game event that occurs randomly (1 in 30-50 chance per 16 hours (configurable)) while users are browsing the stockmarket. Can't really post a link... since it's random and requires a login... ^^;;
