How to change voting widget showing other scales? (A-F) or stars like "Fivestar" or "Note Vote" modules?

How can one achieve this feat?

(As written on the project page:

http://drupal.org/project/userreview

Quote:
Although this module currently permits voting on a 0-10 scale, it should not be hard to have a more flexible scale, such as A+ through F, or any sequence of numbers. This module supports voting on a single axis only (and does not support voting on multiple independent factors like price and customer service).

Please help.
