Hi, Karen - the threads (discussion topics) and messages generally stay there once they're posted. Some get lost in crashes sometimes, but that's rare. If you post a message and later have regrets, post a message in the same thread, asking that the message be removed, and both the message and the request will be deleted by mysterious Mudcatteers with "edit" buttons - or by me, the only one known to have admitted to having such a button. Or you can send me a personal message and ask me to fix your goof. The messages above are better left as they are - they may help somebody learn.
