Now that I’ve started responding to what people are writing, I have a suggestion. If you are writing about your own experience with an exercise, do it in the form of a Post rather than a Comment. Also, give your Post a title (just the first line of the Post, as in this Post) that makes it clear what exercise it’s about. Only use Comments if they really relate specifically to the Post on which you are commenting.
That is not how it has been done right now; instead, people have been describing their experiences with Ex. A as Comments to my original Post on Ex. A. This is not a big problem, and you can keep doing it if you find it easier to do so, but it makes it more difficult for me to respond to individuals.
By the way, it looks as though Comments don’t need to be signed, because the software identifies the writer automatically. Posts, however, do need to be signed.
