With PM's, you MUST check the box that says "I want to keep a copy of my message". If you don't check it, you will not have a copy in your "sent" folder. it's as simple as that.

Posts get deleted for a lot of reasons, usually for being off topic or in the worng forum. So be super careful that your posts are in the right place, and discussing the right things. DB is a lot stricter about this than many other message boards.

Also, posts are often not deleted but MOVED to the proper forum, without the mods necessarily telling you that.
