How to make feeds?

I want to make a feed to follow this blog: http://symposium.transformativeworks.org on Dreamwidth.

How do I make one?

Updating import?

[intertext]

Hi there. When I first joined DW, I imported my LJ blog. Since then, mostly out of habit, I've still been primarily using LJ rather than posting here and cross-posting to LJ. I'd like to start moving more permanently over here, and am wondering if it's now possible to import the blog entries from LJ between when I last imported and now. If I submit another import request, will I get duplicates for the (4 years or so) worth that I've already imported?
