Apparently I don't yet understand the concept of "posts." I've been trying to accumulate five so I can participate more fully, but it still shows that I have only one post. I thought replying to someone else's post counted as a post; I replied to two posts yesterday, fairly early in the day, and yet it still says I've only posted once (plus my reply to the posts still doesn't show up in the replies to the posts). At this rate I'll never be able to participate fully.
