So I read the manual install instructions for Ubercart, and it's pretty extensive. Among other things, you have to install a bunch of modules before you install Ubercart. This kind of makes sense, if you are writing a really robust system for Drupal you are bound to use some of the great stuff already available for Drupal.

You also can not have Ubercart and Drupal Ecommerce (drupal.org/project/ecommerce) on the same site. This is kind of a bummer, as I really wanted to use them side by side to compare and contrast. So, I guess I'll start by trying out the regular Drupal Ecommerce solution before looking at Ubercart.

I had already deleted the Ubercart modules, but I still needed to clean out the database. Luckily, the new ubercart tables all started with "UB", so they were pretty easy to spot using MySQLAdmin to paruse my drupnewb database. There may be a few stray rows in some other tables I should track down and delete, but I didn't find any going though all of the tables quickly.

So, removing a module from Drupal can be tricky if the module is complex and things don't go well.

Hey, I think this counts as my first Drupal mishap! Yay!
