What do people think of Create Space on Amazon.com?

I've written a few novellas (I don't think they're quite long enough to be novels) and I'm interested in publishing and I just found out about this. I don't know much about it as of yet, I'm planning to investigate a little more but I figured people's opinions may be another good place to start.

So if you have any information on how the site works, costs, etc. that would be really helpful and greatly appreciated smile

Hope you're all well heart
