Old browser warning

Site look funky? Your browser is either Internet Explorer (hit refresh (F5) several times due to a bug in Microsoft's code that we can't work around) or is 10 years old and standards-based layouts and styling confuse it. Consider updating. One excellent option is Mozilla Firefox, versions of which are available for Linux, Mac and Windows. Safari 1.0+ and IE 6.0+ are also supported.
