Note: It would be great if there was a way to finagle the code to make the post that goes to livejournal recognize that < user name = "name" site = "livejournal.com" > is the same thing as < lj user = "jennem" >.

That way, cross posts can include the link. I just made a test post and both: jennem and jennem are showing up as plain text on Livejournal.

Note: Text, tags, location, and music all transfered. I haven't tried out the change in user pic, though. Since I used my default user pic in the cross post.
