importer and xpost

[skakri]

Hello, I'd like to know if there is any documentation regarding content importing from LJ-based site (AFAIK, old version, circa "07) and cross-post setup steps? How should I define a new external site?

I'm currently using jbackup.pl + LJ::Simple mash-up, but that won't work in the long run, as even if entry backdate is set, users still receive messages of a new posts, if they're subscribed.
