Is that for the top of a topic? With anchors to each post?
I think I remember someone doing this with a v5 board... do a search in the v5 beta forum and see if it is there... I remember seeing this on a hunting forum or something similar, a guy has been asking me to do it for him, but I haven't seen the documentation yet. I am sure it is possible in v6, just don't know how much of a stretch that would be... sounds like a modification Dave Downin or Leshrac might do... could be possible with the templates.
