Spam Comments & Word Verification
In order to try to combat useless spam comments, I've installed "Word Verification" on the add commments page.
The other option was to stop anonymous posting - but I really wanted to keep that as some of the anonymous comments are from people that I know want to post, but don't want to be named as "one of the bad people" 
So, "Word Verification" it is - it should help to combat the random spam comments.
