Are we allowed only one comment to a story?

It usually takes me a bit to see what I find interesting.

Nothing stops you from making multiple comments. More than once I've received a second comment form the same reader (usually quite some time after the first).

Yes, at times I will reread a story that I had greatly enjoyed and on my favorite or reading list. I sometimes see more to the story that needed a further comment.

It does actually, Rick. There is now software in place to prevent that. We've had quite a lot of multiple comments saying more or less the same thing, and these are being weeded out, or if they contain different information they are being appended to the original. Plus there are instances of the same person making three or four or even more comments on the same story, and that's not really what the comments facility is intended for. So please folks, make just the one comment on a story, and if you want further interaction with the author, send them a pop up as I'm sure they'll be pleased to hear from you.
