@Jeffro As far as commenting goes, what do yo folks think of the commenting form I have on this site? ... this is one of the few commenting forms that gives you the ability to edit a comment for a certain period of time after it’s been published.

The edit-feature is a very good thing, and I use it quite frequently. The Preview feature is also very good, and I use it religiously.

If we're going to encourage and have substantive comments, then most of us will find these particular features very useful.

A spell-checker would fit very nicely with pre-publish Preview and post-publish Edit. In fact, I copy my comment-text, paste it into an e-mail to spell-check it, then copy it again and paste it back into the comment editor .... then Preview it, then Publish it ... and then, not infrequently, (have to) use the post-publish Edit as well.
