Thank you for the feedback Wulf, do you know if Rust Kits
https://umod.org/plugins/rust-kits make use of these ranks. I haven't asked the question on their form yet.
Pookins, great idea and ill put it to us. However im try to when you are VIP to only see VIP kits and when you a default player you only see default kits. I know I can manually add and remove them from the groups to only give them that groups perm. However, I have a online shop so when they buy that package they get added to the vip group or to which group that package is assigned. but they stay in the default group becuase they login to the server. I was hoping for priority or ranking options which would have allowed me to give priority over other groups if they are in different groups and only allow them to see the highest ranked group kits, this will also open other posibilities.
thx for the feedback.
