You have to register before commenting. This prevents abuse from anonymous trolls, sockpuppets and spam.
First time commenters are held in the moderation queue. Don’t freak if it doesn’t show up right away, I have to manually approve you first. This may take longer if you’re sent to the spam queue, as I don’t receive email notifications if that happens. Just try not to look like a piece of spam.
I am waaaaay too tolerant of trolls for my own good, however keep in mind that this is MY personal blog and posting on it is a privilege I grant to you. I am entitled to take it away at my discretion, as it is MY personal blog. If you don’t like it, you can start your own blog. I hear they’re letting people make blogs for free nowadays.
Usually, though, I keep trolls around as chew toys.
