My post replies get deleted

Hello, I was searching on the web for a problem I had and came across a question that was pretty much what I was trying to do. My community profile was not set up, so I did the setup, then went to answer the post. I answered... twice.. because my first reply was gone when I went back to look at it and so, all my replies are gone. What is up with this? Is there some kind of moderation that need to approve posts I do not know about? I was providing my solution to the issue mentioned in the post. That is not very useful for users if replies get deleted..
