Be Gone, Ye Spam!

I hate creating another step in the comment process because I know it will just turn that many more people off from contributing, but our small and loyal group or regulars seems to agree that the spam comments are really annoying and distracting, and I am afraid that the spam will turn off more readers and potential commenters than any extra step in the commenting process ever could, so we are going with a word verification system. Please let me know how it works, and email me if you have difficulties.
