You won't be surprised to find out that we have a comments policy around here. At least to begin with we'll be running comments moderation....sorry, but yes, you'll need to wait for your comment to be reviewed before it is published.
As to what we'll be moderating...the usual legal stuff of course, libel, incitement to violence and so on. Also the usual taste things, no use of the "c" word and so on. But much more importantly this is our blog so moderation will be done according to what we want. We're sure there are any number of things that you might want to inform us about but this may or may not be the time and place to do so. If we decide it isn't then there is no appeals system. Simply go and get a blog of your own and start posting.
