Choosing a different template

From Documentation

68 Classifieds comes with three different templates which you can use. To switch your site from using the default to a new template you would login to your administration and then go to main settings. Next you would locate the select field beside "Site Template" and change it. This change is global across your site and anyone browsing will now see the new template.

If you wish to view a template but not actually switch it for everyone you can visit your site's home page and change index.php to index.php?template=newtemplate to the url. newtemplate must be a folder inside the templates directory before it will pick it up.
