Sorry, but I've disabled comments on the blog for now as the spammers are particularly active and the only way of dealing with them on 20six is to disable comments, which annoyingly hides all of the previous ones.
As I've now moved to Blogger, who do a great job of spam management by the way, I don't want to have to log in here two or three times a day just to clear out the spam comments about fake handbags and Ugg boots, to name but two.
If that's caused you a problem then do let me know
