Under SEO there's an option to tick using friendly URL's to get rif of the "index.php?" in the web address. Should I tick that? Underneath it says
"If you enable this option, the links generated by the system will not include "index.php?". However, to enable this, mod_rewrite must be available and an appropriate .htaccess file (or the equivalent for your web server) must be in place."
I seem to remember there is an .htaccess file in the forum software on the server so assume it's ok to tick that.
