Now that everything is almost done I was thinking to tell you something

about the reputation system.

A reputation-based system is characterized by two facets:

• each user collects a personal reputation reflecting his perceived

utility to the community,

• the effect/weight of his actions in the community depends on his reputation.

We have created our reputation system to evaluate and encourage

several facets of the student participation:

• Involvement

• Usefulness to others

• Competency on the topic

• Ability to judge other's solutions

• Critical thinking (while correcting other's work)

The total reputation is obtained by weighting the 5 facets as follows:

reputation = [

2 * involvement

+ 3 * usefulness

+ 5 * competency

+ 1 * judgement

+ 4 * critical_thinking] / 5

Further on another day :P
