Points collecting for user level?

I want to make a system with points - as more active is an user - more points he collects and increase his level on site (silver, gold member and so on)

Is there an option a user to get points when posting comments (photos, guestbooks) and uploading materials ?

I strongly suggest that you go to expertzzz.com and begin to look through all the modifications/upgrades & plug ins that are over there.
