If you don't want to edit template, according to me, go to additional.css and add css
.blockrow ol{display:none;}
to hide that block.

That will hide more on the site than just that. You really think that is the only place on the whole site that uses that class? :)

Sometimes its more useful to know why someone is doing what they're doing, instead of what they think the end result should be. In some cases you can lead them to a better destination.
