this blog entry has been updated
Back in April, 2008, I optimistically wrote that we would update the commenting system to allow threaded comments "in the near future". (Not surprisingly, I wrote this in response to a nasty troll.)
Today I'm happy to announce that, almost three years later, RTH finally has the threaded comments I've been promising all this time.
The way it works is pretty simple:
To post an original comment, i.e. not in reply to another, simply continue to use the comment form at the bottom of the comment area.
To post a reply, click the "Reply" link at the bottom of the comment you want to reply to, and a reply form will appear below the comment. If you click the "Reply" again, the reply form disappears.
Replies will show up beneath the parent comment, indented slightly on the left side.
Whole threads can be collapsed or expanded by clicking the blue [ - ] symbol at the top of the original comment.
Try it out and let me know if you run into any problems.
Update 3: I have implemented the ability to switch between nested comment threads and the original flat comments. At the top and the bottom of the comment list are links to View Comments in Nested or Flat format.
The site saves your selection as a cookie so that subsequent pages will be served in your preferred format. This should work for both registered users and for anonymous visitors, as long as you have cookies enabled.
Update 4: I just realized that a child comment of a comment that gets deleted would be orphaned. I've updated the code so that child comments of a comment about to be deleted are attached to the parent comment (or to the OP root if there is no parent comment).
Update 5: I updated the code so that even if you're viewing comments in Flat view, you still get a link to the parent comment of a reply.
