Personally I only use IE, and sometimes Firefox if I want to be logged into two accounts at once. Firefox is great for add-ns to help with Rping, but in the end I just prefer IE because that's what I'm used to - and I'm pretty sure a lot of people are actually the same. They just don't pipe up a lot lol I wouldn't know how to make that particular layout work for IE, but I'd suggest going with something that is compatible with that also. You wouldn't want to lose potential members just because of something like the layout!
