you have some thoughts about what to do with those pfiles?

They are added to the in.relation.to repository directly. You can find them under the importer directory. They are bzip compressed and did not take much space in the end. The files in question are:

• posts.pstore.bz2 (the actual blog post data, keyed against the lace url)
• users.pstore.bz2 (the bloggers home info)

I don't think we need to do anything more here.
