Also submitted this info on github - this one feels more like a bug:In osticket 1.9 RC1, downloaded 5/1/2014, we spotted what appears to be
an issue in include/client/header.inc.php . There is a section of code
that displays the text "Guest User" (lines 55 and 56) based on the
client registration mode being public. However, if the configuration is
such that clients must register (a new feature of 1.9), then
displaying "Guest User" makes no sense as their can never be an actual
guest user. The test $cfg->getClientRegistration() == 'public'
should likely be OR'd with a test for whatever variable corresponds to
the field Admin page => Settings => Access "Require registration
and login to create tickets".
