The way i was thinking about using this would be by using the built in support that invision has(trying to verifiy youtube accounts). They submit a support ticket for verification,i create one manually and give them the code,then they send me a link back to an unlisted video with them telling me the code i sent them.
Would that be possible with this? Also do they get a check by their name so everyone else can see that they are verified or does it just use the secondary group for that?
