YouTube Video Display Vanishes Upon Skin Change
Using Jamroom
The Menu Editor is for the user drop down menu (the drop down menu next to the ACP drop down menu). It allows you to add more links to that particular drop down.
To add a link to the main nav menu, you'll want to modify the header_menu_desktop.tpl file. This can be done in your ACP > Skin Settings > Skin Templates. Or by modifying the template in an editor and then uploading to your site via FTP.
By using the template editor in the ACP, if something should get messed up by your modifications, there is a Reset button you can use that will revert the template back to the original template code.
You won't need to know any CSS, although it is recommended for any website, its just basic HTML for the menu. If you need it to be multi lingual then you'll need to know how to use the jrCore_lang function.

So if you go to your ACP > Skin Settings > Skin Templates and click the modify button for the header_menu_desktop.tpl, you can setup a new audio link by adding this:
<li><a href="{$jamroom_url}/{jrCore_module_url module="jrAudio"}">Audio</a></li>
just above this code:
{* User Settings drop down menu *}
{if jrUser_is_logged_in()}
<li>
<a href="{$jamroom_url}/{jrUser_home_profile_key key="profile_url"}">{jrUser_home_profile_key key="profile_name"}</a>
<ul>
{jrCore_skin_menu template="menu.tpl" category="user"}
</ul>
</li>
{/if}
And a YouTube link would look like this:
<li><a href="{$jamroom_url}/{jrCore_module_url module="jrYouTube"}">YouTube</a></li>
Hope this helps!
