Hi,
putting customized files into usersc is great. I'm not sure if it is documented, but the path to the init.php has to be adapted for files in usersc, of course (this was repeatedly in the forums). It is clear that also other paths must be adapted, like 
require_once("includes/recaptcha.config.php");
in join.php and others.
Would be great if this information could be added explicitly e.g. to the "General Documentation".

Thanks,
Sebastian
