I just wanted to add, that there are many other logical fallacies, such as ad hominem, appeal to authority, straw man, beggin the question, false dilema, red herring, slippery slope, etc.
There are many sites on the web that explain them, and I'm not sure that I've found a completely comprehensive list yet. Here is a site that lists many of them:
