This is an interesting comparrison of Mormons and traditional Christians:

The issue of whether or not Mormons are Christians is pretty interesting, I think.
Here's what I've gathered:
Mormons most definitely consider themselvs to be Christians (after all, the name of their church is "The Chruch of *Jesus Christ* of Latter-day Saints". Most mainstream Christians do not consider them to be so.
It seems to me one of the biggest differences is that Mormons are polytheists -- that is, they believe there are many Gods in many universies (although they only worship the one, I believe), whereas mainstream Christians are monotheists. The other big one is that Mormons don't really believe in the "Trinity" idea -- they believe in the Father, the Son, and the Holy Ghost, but they believe they are three seperate persons.
In the end, I think the answer to the question "Are Mormons Christians?" depends on your definition of the word "Christian." If your definition of a Christian is simply someone who believes that Jesus Christ existed, redeemed us, died on the cross, rose from the grave on the 3rd day, and will return to Earth one day, then Mormons certainly qualify as Christians. If your definition is more strict, then they might not be.
