Well, it's certainly a lot more readable, and for the vast majority of (non-member) readers, that's the important thing. E-mail headers are likely to be of interest to only a handful of folks, though I suppose the lack of them might give some people an avenue for claiming forgery.
I guess the question is, do we care about those people? I wouldn't think so, but of course I wasn't personally involved in any of these cases/disputes, outside of my (mostly tangential) role here on WR.
Thanks for doing this, btw - and if you're not doing it with some sort of script thingy, I might have a little time this weekend to help reformat some of the stuff.
