Okay, so I tried the comment moderation and what I like about it is that I can delete the spam and it never even gets a chance to show up on the blog. What I don't like about moderating the comments is that the conversations between fellow readers has been slowed down quite a bit and that part was always fun for me because I like when many of us are involved in one conversation, instead of just me interacting with everyone individually. I am removing comment moderation for the time being and hopefully those organic conversations will return. We will just have to ignore the random spammer who leaves the same comment over and over and over - and don't click on whatever link it is they want you to click on!
Thanks everyone for putting up with my changing things all the time.
