This is a bit of a different blog candy posting, because Christine points out the merits of turning off word verification. I must admit that I used to have it on and then for ages took it off. I did get a bit of spam, so put it back again. However, I've now taken it off because in the grand scheme of things it doesn't make much difference and is probably an annoyance to visitors to my blog.
Christine is one of the team on the new BG challenge blog.
