Thankyou very much for the unprecedented amount of comments I found in my moderation queue over the last few days. Very informative, but just so you know I don't need any of the gambling facilities or drugs you all recommended. I've just activated Akismet to see how that goes - I was very impressed that it comes as standard with this version of wordpress (2.0.3). All I had to do was sign up at wordpress.com to get an api key.
