Thanks to Richard and Feargal for letting me know about problems adding comments to my blog. I’ve tried it myself and it seems to work OK, so I’ll have to try and do some detective work… I love bug fixing! 🙁
Apologies to anyone who is unable to leave a comment. I’ll post again when I think that I’ve fixed things.
Update: I’m hoping that comments should be working again now. But, the problems were only affecting some people, so it is hard to tell.
