I am putting a button in the side bar and making a plea to all my fellow bloggers. I have seen this on many blogs and I agree, please please please switch off word verification. By all means keep the moderation on, so you can approve the comments before they come live.
I know google recommends this to be on, however in all the time I have blogged I have not had any spam comments and as you approve them before they go live, you can delete them if you do get any. I love looking at all your blogs and to leave feedback, however when you visit many blogs word verification takes time. Then you get it wrong, and it takes time for it to go through.
I am now putting this in my side bar, please switch of word verification.
