Kind of hard to explain here, but i'll let you know. Those types of scripts would not be hard at all. Do you have a gaming site? or are you in the process of creating one? Or what type of website will you be using these features on? If you need a programmer please feel free to contact me. I have years of experience in PHP & mySQL, just ask around here.

Contact me if your interested, or if you need some help with anything.
