I can't find anywhere listed on this the permissions I need to add so this works.  Anyone point me to where they are listed or what they are?

duelist.dd is the only permission I see, which is show on the plugin's page.

Ok will have to try that.  Hey I got a question, Since this last update a lot of my rust plugins are showing color codes like <color='green    instead of doing the color.  Like I have the Licence plugin.  When I type /buy it shows the error.  But some mods, the colors are working and showing.  Any idea of a quick fix?

You'd have to edit wherever the color names are and use hex codes instead; in the plugin, lang files, config files, etc.
