It's quite simple
in your gmcmds.cpp you have under every if the following code
- if(Config.Command_<name> > thisclient->Session->accesslevel) {
- // the code of the command <name> ...
- }
If you change > to >=. The commands can be written as the exact accesslevel as they should.
- if(Config.Command_<name> >= thisclient->Session->accesslevel) {
- // the code of the command <name> ...
- }
