chriswe, I can understand you being cautious about installing modules etc. You've made 3 posts here, so I guess you are somewhat inexperienced with xoops. My advice is always, install a local environment of XOOPS using something like
WAMP and experiment with a local version of XOOPS first.
Read
presentation to find out more about wamp. Put
simply wamp provides a basic but complete webserver on your computer that is the same as your host offers. this allows you to run a complete version of XOOPS (or other webserver scripts)
This will get you used to all kinds of operations and procedures, without fear of messing up a production site.
Xoops protector is IMHO an essential module and ideally should be integrated into every installation.
