I am still having problems. I have changed the register_command line in my module from
$this->register_command('all', 'myguildname', 'GUEST');
to
$this->register_command('all', 'myguildname', 'ANONYMOUS');
The above still has exactly the same problem with non-members not being able to use the module. Is there an additional setting that I need to change somewhere, and if so, how do I get to it?
