Blogger forced me into the new interface a couple days ago. I didn't like it when it was in preview mode, and I don't like it now, but I'll adjust. One thing that has improved since I looked at it when I wrote about blog comments in February is that I am able to find the option to turn off word verification. To do this in the new interface:
1. Get to a page that has options listed along the left side of the page. I'm not sure if this is still called the dashboard or not.
2. Click on Settings.
3. Click on Posts & Comments.
4. Look for the dropdown labeled "Show word verification" and select "No". (As of a week or so ago, this was defaulting to yes regardless of whether you'd already turned it off, but they seem to have fixed that bug.)
5. Click Save Settings button in upper right.
And I do still urge you to consider turning off word verification. It hasn't been getting any easier for me to decipher the wonky images, for sure. When confronted with them, sometimes I just click away and don't bother. Sometimes I persevere, and if I'm feeling especially energetic will add something to my comment about turning off the option. I know that some bloggers who have it on aren't doing that to vex me but just don't realize it's on, because Blogger won't make you do it on your own blog. So if you ever come here and find it's on, be sure to let me know!
