Thread:Project:Support desk/delete tabs view source, view history and read/reply

This is one of the most common, if not the most common question here.

You find ideas in Thread:Project:Support_desk/How_can_I_hide_tabs_for_users_not_logged_in%3F; the idea there is to take the tabs away before MediaWiki renders them. Another idea would be to hide them with CSS, which might be a bit easier. However, I would prefer the cleaner solution: Take them away before rendering.
