Storefront question
In the book, you talk about installing a second copy of drupal (and associated themes/modules) at {root}/store/ to simplify ubercart installation. That seems to make sense, but what do you do for a database?
If you create a second MySQL database for the store, then user registrations wouldn't match - No user likes two account setups for one site.
If you try to use the same MySQL database, then modules that appear in both the {root} and {root}/store/ sites might overwrite each other. (Or is that actually an advantage as it keeps the two installations consistent?)
I'm adding a store to my site and while I like the {root}/store/ idea, I'm worried about implementation. Any thoughts?

I would use one installation and one database, and have customers login if they want to make a purchase. Ubercart will take care of cataloging for you. You will find it much easier to maintain and use.

Do you need a login on the first site? Why not just include a login for the store site only?
I would run both from one installation and use pathauto to get the /store to show properly.

You would need a login from the first site for userid maintenance and password reset/retrieval.
But essentially you've answered my question - One site is simpler, and IMHO, preferred. I wish Lynn would step in and explain her reasons for two sites ...
