Sorry if I am late, but,
i am currently creating a rework of RTB's admin control system that is based off of time played (moderator and higher won't be earned by time played), so you can jump from a guest to a Regular player (requires 2 hours of server time), then to a Royal/dedicated player (requires at least 5 hours played, diff time tba), to a VIP (requires 10 hours of time played on the server). there is also a custom clan rank that SAs can change the name of so you can make your clan members join your full server or join your passworded one
1. This is a terrible way to give admin/VIP out, lol
2. I have tried to make it so people can get it without a password needed, but it seems to be hardcoded into the engine.
