[ic] Bonus points as currency

[Albert Hauck]

      I would like to build a small shop system that is accessible only for
registered members. Each member collects on a user account "bonus points"
(by doing some registration actions). These poins should be used as currency
to buy goods. Do I need to implement a payment module or is this possible by
using some built-in mechanics. Did anybody realize a similar solution and
has some hints for me? How could one program the account information, that
shows the members the history of their account transactions?

      Thanks in advance, Albert
