Here’s a general question for everyone about how to make comments on comments.
When we “Reply” to a post, the first reply is displayed hard against the left-hand margin. The next reply is a little more to the right, or “nested”. The third reply is even further to the right, and so on. Eventually a limit is reached, or replies would have to be displayed in the width of a single character. WordPress defaults to 10 levels of nesting. After that, all replies are indented by the same distance, but you have to scroll up a long way sometimes to find the related Reply button.
Long ago I reduced the number of “Replies” possible from 10 to 6.
A maximum of six replies is inadequate, but so is ten. I lean strongly towards reducing it to zero, putting all comments at the same level and removing the problem entirely. But it would introduce a new problem, of identifying in a possibly long thread the comment we are responding to. We would have to somewhat carefully specify the “NAME at DATE at TIME” we’re answering and that would be a new discipline for us.
Would that be all right?
