When preforming a custom search you get a series of tabs such as:

* Binary poll
* Board
* Character
* Fleet
* Google
* Issue
* Log entry
* News
* Note
* Page
* Project
* Ranking poll
* Webform

Most, if not all, of these result in 'Page Not Found' errors. This is because the generated URLs contain and extra 'webb' subdirectory. For example, http://www.star-fleet.com/webb/webb/node/add/advpoll-binary.

I do not know what the purpose of these tabs is however, but I guess that they are meant to create various content types which are denied to the normal user.
