Maybe use the Reports function under Logs (bottom of the page) to export to Excel, and then do a mail merge-type thing into a better- formatted document?
Do you want the comments attached to each post, too?
I have a script that grabs all the training data (just from the reports option) and it would be easy to spit that out in a custom way. Would be a bit trickier to grab all the comments but certainly doable. Or maybe ken already has an easy way...
