I don't know if it's the service or the plugin (that interfaces with the service), but this needs work before it's ready.
I just spent 35 minutes replying to a post -- first as an unregistered user (oooops! I thought I was logged in as admin. I guess not?) -- then in approving that comment it posted a second comment.
Hmm. Ok, let's delete the second comment. Done. But wait! It's still showing up. Why? Ok, so let's go back in... now the second comment is somehow INSIDE the first comment, actually part of the first's text. At that point I set it down. The cost/benefit ratio of this isn't there for me.
This should be beta software it's such a mess.
