FYI, effective right now I’m turning OFF the CAPTCHA requirement for posting comments and very unfortunately switching back to requiring comment moderation.  I just tried posting a comment to one of my own posts and found that TypePad kept requiring me to re-enter a CAPTCHA – endlessly.  I did it about 8 times before I just said “enough is enough” and went into the TypePad control panel and switched back to moderation.  I first heard of this issue when a comment was left on an earlier post last week and I’ve commented successfully since then… but this was the first time I’d seen the issue myself.  I’ll file a help request with TypePad to report the issue, but in the meantime thought I would raise the issue here.  (And now comments will get through, but of course won’t be published until I approve them tomorrow.)
