A "My Posts" button.

I use Gametrailers forums alot and they're using vB aswell. They use something over there that tracks all your posts and shows them to you, much like we have but without having to track through finding your profile.
It's just simple for people who have done a specific thread to ask a question and want to check up on it.

Do they call it a search button?

As thats your best option for finding things.

There really isn't a point as you can simply just click your username on the post bit and click the View all posts button ;).

isnt that what the subscribe button is for?
