Of course, every time you now type 've' in the address bar, ve.com will be first on the list - but selecting 'Clear History' gets rid of every site you've visited, so it's a bit of a harsh solution.
In Safari, you can open up your bookmarks by clicking the icon on the toolbar, view the history folder, and delete single entries from the history (click once and hit the delete key). Delete ve.com, and when you type 've,' you'll once again be offered versiontracker.com.
