If you don't mind using a script for it, someone requested one before so I wrote it.
- script GMLimiter -1,{
OnPCLoginEvent:
if ( getcharid(3) == AccountIDHere && strcharinfo(0) != "GM Name Here" ) { atcommand "@kick "+strcharinfo(0); }
end;
}
Just duplicate this line for each account/character
if ( getcharid(3) == AccountIDHere && strcharinfo(0) != "GM Name Here" ) { atcommand "@kick "+strcharinfo(0); }
And don't forget to put the proper tabs in the first line.
