Where do I change the text in the top?

most probably it is in header template

admin panel --> templates --> active set of templates (depends on your current theme)
--> header templates --> header

general menu links code

<div class="menu">
				<ul>
					<li><a href="{$mybb->settings['bburl']}/search.php"><img src="{$theme['imgdir']}/toplinks/search.gif" alt="" title="" />{$lang->toplinks_search}</a></li>
					<li><a href="{$mybb->settings['bburl']}/memberlist.php"><img src="{$theme['imgdir']}/toplinks/memberlist.gif" alt="" title="" />{$lang->toplinks_memberlist}</a></li>
					<li><a href="{$mybb->settings['bburl']}/calendar.php"><img src="{$theme['imgdir']}/toplinks/calendar.gif" alt="" title="" />{$lang->toplinks_calendar}</a></li>
					<li><a href="{$mybb->settings['bburl']}/misc.php?action=help"><img src="{$theme['imgdir']}/toplinks/help.gif" alt="" title="" />{$lang->toplinks_help}</a></li>
				</ul>
			</div>
