I am sure this has been asked and answered before but I can't find it...

Can I install XOOPS on a site that is a live static html site using index.html as the main index in htdocs to test and configure XOOPS without adversely affecting the live site and if yes do I do so with the standard install instructions?

Part two (less critical but still of great interest) - is there an import into the forum from wwwthreads or gossamer threads or a way to integrate either of those two into the user login so users don't have two differnet logins on the site?

Thanks
