Ah, you're using UBB.threads then. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />

Enter the control panel, click Forum Settings. For each forum on the resulting page, click the Details link on the far right. Look at the Permissions tab, and at the very bottom, you'll find the permission matrix. Change the Guests group from its current setting to Read Only, then click the submit button at the bottom of the page.
