Looking for help setting a new wordpress up…(spam related)

I have 1.5-beta-1 2005-01-04 running already at iconoclastic.polarism.com

I want to take the stuff i’ve already written, delete the current installation, and start fresh, only here are the stipulations:

Whatever I have to install or modify, I want zero chance of spam, I do not care what I have to do (as long as it’s free), I do not want spam. I’m not a programmer so this solution has to be very small amounts of editing or just copy/paste.

I just want to be able to write and have comments without worrying about it, I don’t care what version I use, I don’t care about anything other than it looking like it looks now.

Thanks, ??
