Can anyone help me code this properly? My biggest problem is the mainnav drop-down in IE. I've checked Safari and FF for Mac and PC. It's just this IE positioning giving me a problem. I'd prefer not to hack it, but anything to get it working at this point would be nice. The subnav is also displaying different than intended, but it's not a major problem. Also, the fonts are so much bigger in IE, I'm using ems, should I be using something else to get a more accurate font display?
