Crossposted post ids' variable?

[ari_linn]

Hello,

I want to know how to make a link to an LJ crossposted post. See, I'm posting something into DW and it gets crossposted to LJ. It leaves a link to the original DW post in a crossposted LJ post:



I was thinking that it would be nice to have a link to the crossposted LJ post in the original DW post as I didn't see it anywhere.



But the link was nowhere to be found until I stumbled upon one of my friends' friend page that showed my DW post with a link to the crossposted LJ post!



I don't know what theme he uses, but it seems like it's something unmodified and pure DW. I, on the other hand, use a custom theme that is basically copypasted from LJ's Smooth Sailing theme (I was given an instruction how to copypaste it here in this community). Now, I want to add a link to my crossposted LJ posts to my custom theme. Is it possible? I think I'm savvy enough to modify the theme code provided that I know the variable that holds LJ post id.
