[support] Customizing Drupal Commerce

[techlists at phpcoderusa.com]

Hi,

I am looking at customizing Drupal Commerce.  I've been a LAMP dev for a 
while however I am very new to Drupal.  I have a ton of questions.

First let me say thank you for all your help and guidance.

I am wondering the best way to proceed?  Hack the existing commerce 
modules or create other modules that interact with the existing commerce 
modules?

Thanks again for all your help!!

Keith
