01. Can i edit any of your layouts? Add a Header? Change some Colors?
NOT UNLESS YOU KNOW WHAT YOUR DOING. I usually don't mind, but if you change something and it messes up the codes, please do not bombard me with questions of "can you fix it?" because editing it was your choice. I cant keep answering 100 questions of "Can YOU fix my mistake?" - its taking it's toll on me. AND DO NOT REPOST WITHOUT CREDIT FOR THE STYLESHEET! - i know my own codes.
http://minty-peach.livejournal.com/ Your layout looks fine in Internet Explorer; what resolution are you and your friend's screen at?
Also, a screenshot and a more detailed description of the problems would really help us. We're good, but we're still working on the mind reading thing.
