Oops, looks like I inadvertently upset Mikal, which wasn’t intentional!
The only reason I got a little miffed was because I got a message that instead of saying “1 comment held for moderation” said something like “1 spam comment removed, you can be the first to leave a real message“. Anyway, it’s all fine now..
I’m using the Akismet plugin to WordPress (now a standard part of the install) which does a damn fine job of spotting spam.
