Thanks for the great plugin. I'm using it to create a whole heck of a lot of posts, and I noticed it's pulling the data from a server. I'd like to request a feature be added to use a local piece of data as the source, in order to speed up post creation (to give you an idea, I need about 60,000 posts). If you're interested in the feature, but don't have the time, I can probably look at it and submit a patch sometime in the future.
Thanks again for the hard work!
