Open /modules/system/templates/blocks/system_block_mainmenu.html in your editor, and just place the link to the page you want added to the main menu.
Here is an example:
<table cellspacing="0">
<tr>
<td id="mainmenu">
<a class="menuTop" href="<{$xoops_url}>/"><{$block.lang_home}>a>
<{foreach item=module from=$block.modules}>
<a class="menuMain" href="<{$xoops_url}>/modules/<{$module.directory}>/"><{$module.name}>a> <{foreach item=sublink from=$module.sublinks}>
<a class="menuSub" href="<{$sublink.url}>"><{$sublink.name}>a>
<{/foreach}>
<{/foreach}>
<a class="menuMain" href="<{$xoops_url}>/">yourtexta>
td> tr>
table>
