Other forum engines, and even other forums using this engine, have an easier way to find your own posts than manually finding one of your posts, clicking your name, and going to "find more posts"

Ideally, you'd be able to click your name in the upper right where it says "Logged in as _____" and it'd take you to your homepage, where you'd find a "find my posts" and "find threads i've started" page. For an example, this is how Gateworld's forums (forum.gateworld.net) works and they use vBulletin too.
