Now you have a post count of 2. They are probably both from this thread. I just did a little experiment... It looks like anything posted in the The Lounge (off-Topic) section does not count towards your post count. I am not a moderator, but I suspect that they put that in place because certain features (such as private messaging) are only activated after reaching a certain number of posts. I guess that they wanted those posts to be on-topic, or at least forum related.
