Spam
Another of my boring-but-necessary posts, I’m afraid. Spam is getting ridiculous here (though not as bad as for some, I’m sure!) so I’ve had to take measures to reduce it. I’ve just installed Spam Karma which will hopefully reduce it - but there’s always the risk of some false positivies. So if you post a comment and it doesn’t turn up drop me a line on [gilmore at physics dt uq dt edu dt au] where “dt” stands for dot! 
I’ll have a look and reinstate the comment Sorry for the inconvenience, but hopefully this will cut down the time it takes to delete spam.
