Ooh, change! Sort of scary. Especially when I just made the change to this here Church of the Churchless blog.
Even though it isn't holy (except to me), any fiddling around with blog features, particuarly beta ones still in testing, is a bit anxiety-producing.
So far, the new commenting feature seems to be working fine. That's based on one comment I just left to the previous Krishnamurti post.
Let me know, via the email link to the left, if you encounter problems. I'm as new to this as you are, just about, but will do my best to answer questions.
For the moment I haven't activated the "show photo" option for people with a profile. I'm not sure if I want to see a photo of myself next to every comment I post, unless I upload a more youthful image.
[Update: changed my mind...it's activated. Decided that I'd enjoy seeing photos of commenters. Or whatever other image they wanted to associate with their persona.]
I don't believe you have to sign up for a profile in order to leave a comment. There are advantages to having a profile, though, as described in this FAQ, and itemized in the image above that I grabbed from the profile sign-up page (click to enlarge).
So I encourage you to sign up for one (if I decide to turn on the photo feature, you'll be all set to see yourself next to every comment you write).
I've deactivated the requirement to enter those anti-spam "CAPCHA" letters/numbers, so leaving a comment should be easier now.
A primary reason why I wanted to move to this new commenting feature is that threaded comments are possible with it. Meaning, you can leave a comment under another comment, which makes it easier to follow a conversation on a topic.
Since comment conversations sometimes take unpredictable and curious turns, far away from the original content of the post, this is a good thing.
