hm - think I should post this as its own top-level post? This is it:

<span style="font-size: smaller;"><a href = "%%url%%">Original post on Dreamwidth</a> | <a href = "%%reply_url%%">Leave a comment on DW</a> | <a href = "%%comment_url%%">Read %%comment_image%% comments on DW</a>.</span>

(oh thank god for comment preview, I originally forgot to hand-code the < and > in. You nearly got a footer. *facepalm*)
