I took link underlines off by placing the following HTML into the Analytics Coding Area...
(( I DIDN'T KNOW HOW TO PUT THE CODE ON HERE FOR YOU TO READ WITHOUT PUTTING SPACES BETWEEN THE "<" AND ">" BRACKETS, SO JUST REMOVE THOSE SAPCES. ))
You can also manually type the "< u >" and "< /u >" codes into your blogs, etc, and it will individually override the code you put into the "Analytics" area. That way, when you feel it's important to underline text or links, you can have it on an individual basis.
