[Zope] Newbie question: adding a tinyTables object

I'm running Zope on a Win98 machine; downloaded, unstuffed, and installed tinyTablesPlus folder in the lib\python\Products directory. TinyTablesPlus shows up in the product list of the Control_Panel/Products folder of my Zope installation. But it does not show up in the Available Objects pull-down menu in my Zope content folders. I can't figure out how to Add a TinyTables object. Can anyone help? Richard
