Believe it or not, this started out as GWB's style sheet.I think you made too many improvements to bother giving me any credit. This is a real knockout, John! I really like the dark art look. Maybe I'll try for the Mary-Poppins-too-much-Prozac look for some contrast.
If GWB is right and there will be a user level option for how many posts to allow per page, that would be fantastic. The benefits of breaking a thread into parts, to those with 56k and less, and also to the web server cache would be great. There are many of us though that have high-speed access and 100, 200, or even 500 posts isn't a bother.
I also looked more closely at your example and noticed that there was an "old style" link, that's kinda cool. That would be beneficial to those who have the "fear of change" bug. But I would further suggest that you throw that in at the user level too as it would get kinda annoying to have to click that on every thread you read if you are one of those users. Especially if you have 100 posts set as a preference, on a 56k connection, and have to wait to see that link to download "again" the thread.
If I may be so bold as to offer one more suggestion. Something I think I've mentioned in a "wish list" thread before. And since you've already made changes to the post form, I think its prudent now. Could you please put the post the user is replying to on the bottom of the post page? This makes it much easier to get your point across. The current software does a great job of allowing you to go back without losing what you typed, and I realize the user could always open the reply in a new window. But consider it like a "one-stop shopping" environment.
Thanks.
For rolling up stylesheets to test with, it would be good if the thread had some BLOCKQUOTE'd text in one of the replies. I didn't find any. Also, an example of highlighted text would be helpful.Can't help with the highlighted text (can't get it working with any style sheet/browser combo), but here comes an example of fr_quote (do load something that recognizes it for effect; without it, you'll just see something that looks like it's been <br>'ed):
