Ahh, thank you. You know, I've looked right at that part of the FAQ before, but at the time I was in the process of choosing an email service based on features, so I was paying very little attention to things like style sheets, and it just didn't sink in.
I must say, Winstream has to be the best for reducing scroll (and I did test them all with precisely that in mind). My only complaint is that some of the text becomes darn near unreadable on my notebook screen. If it wasn't for that, I'd be using Winstream. I love the way it allows me to run with the 1280x1024 (Very Large) setting without scrolling, even with my monitor running 1024x768.
