You can also click on your username in any thread, and click on the menu option that says, "Find more posts by your-username."

Misplaced, you are a new member, and as such, all of your initial posts have to be reviewed by a moderator (as we note in the welcome PM to each new member). You can't view or review your posts until they've been approved by a moderator (which can take up to 24 hours, but usually is done within a few hours most times).
