I installed the plugin in a testsite and it looks good.
I plan to use the software for a site for people with mental illnesses, so all the channels should be private.
In the options within WP I can add two channels, but the most recent version of PHPFreeChat says 'multiple channels' are available. Does this mean the wp-plugin is not the most recent version of PHPFreeChat? For now I can't see how to set up more than two channels.
