Comment improvements (I hope)

I am quite gratified at the flow of comments so far here at Diabasis — I’ve received many excellent ones already.

In hopes of improving the commenting experience for readers, I have put in a pair of minor changes, which I hope will improve functionality, especially for readers who wish to discuss posts with each other.

First, I have tweaked the settings to allow nested comments.

Second, in an attempt to follow up on a suggestion from one of my excellent commenters, I have installed a plug-in to allow commenters to receive notification of follow-up comments.  I haven’t been able to test this very extensively yet, but you should notice a checkbox at the bottom of each post’s comments that will allow you to subscribe to e-mail notifications whenever someone leaves subsequent comments on post.

These changes are experimental and I hope they work.  As always, I would appreciate feedback.
