WordPress-to-LJ crossposting with custom fields.
I've tweaked the plugin to include the related link in LJ crossposts, so folks can make with the clickie directly, as opposed to needing to come directly to the post.
Information on how it was done is available here, in case anyone else is trying to figure out how to add their own custom fields.
Apologies to the LJ folks who have been getting extra friendslist clutter. No more, I promise -- at least until the next issue crops up. ;)
