So, the only plugin I can think of that can move users around in Permissions Plugin groups is Essentials. Since there's no unified permission system it's a bit too complicated for me to rewrite my old plugin (half of which was blatantly copied from a simple rules plugin anyway). What I need the plugin to do is: a) Display the rules from a .txt file with the /rules command b) Move users from one group to another (Permissions plugin) i.e. guest -> trader after typing another (configurable?) command, in my case it was /accept_the_rules (yes, long and hard to type out :3) This would work nicely if one disabled build permissions for the default group, which I plan to do. For reference I attached the source code of my old plugin.
