I heard that Ubercart is a marvelous module.
So I gave it a try after reading its documentation at the official website.
It's very frustrated trying to figure out how to customize this module.
Its documentation just contains the basic setup, so it's almost useless for me.
I read this module can be used to sell service which is expired within some periods (days, weeks, or months).
And I also read that I must installed "roles" module for this purpose.
But that's all. There is no example how to set it up.
I have activated that module, set its setting in the "product setting" page and still wondering how to make it works!
So where can I get some helpful information about this module?
