This modification is included in the Shiny Black Skin by Staircase :

The skin comes with a scrolling marquee. You can either totally get rid of it OR
you can edit it.

To edit it, edit your templates in the Admin CP. Go to Forum Home Templates ?
FORUMHOME. Below $navbar, there is a code like this:

<table class="tborder" align="center" border="0" cellpadding="6" cellspacing="0" width="100%">
<tbody><tr>
	<td class="tcat" align="center">
        Notice from the ADMINS!
	</td>
</tr>
</tbody><tbody id="collapseobj_forumhome_welcomepanel" style="">
	<tr>
		<td class="alt1" align="center" width="101%">
        <marquee>READ THE ANNOUNCEMENTS!! You could be banned if there is
        something important and YOU DON'T KNOW IT!</marquee>

		</td>
	</tr>
</tbody>
</table><br>

You can either remove it fully or you can edit:

        <marquee>READ THE ANNOUNCEMENTS!! You could be banned if there is
        something important and YOU DON'T KNOW IT!</marquee>

and:

Notice from the ADMINS!

if you want to change those.
