Hi, I have a website (HTML, CSS) and now need to add an online store. I am thinking about Zen Cart - but have some questions....

First, can users buy products without being logged in?

Second - about installation and customization:

- Can you install using dreamweaver?
- Can you preview before going live, or only customize in live state?
- Can I add zen cart elements to my current products pages/display?

Thank you!
