I wanted to make a whole suggestion just about commands. I'm not sure what commands are in and what aren't but for implementing them, this should be a good list.
Player Commands:
::char,::look - Change your characters appearance
::players - Check how many players are online
::afk - Your player will yell I'm AFK
::info,::help - Usually pulls up help for the server
::yell - Yells a message across the server where everyone can see
::commands - Pulls up commands list (Usually)
Moderator Commands, Admin, Owner.
::noclip - Allows you to walk through walls (I don't like this one too much, but it could be useful for stuck people. I don't know this is a touchy one))
::tele ####,#### - Enter numbers in the #'s, this will teleport you to the coordinates you entered.
::xteleto- Insert the players name after it to be teleported to that player.
::kick, ::kickuser - Kicks the player off the server, enter a name after the command
::mute - Will mute the player specified
::ban, ::banuser - Bans the user specified
::ipban- Bans the ip adress of the user specified.
::jail- I don't know if we have a jail, but you have to enter the players name.
::god - Enables your character to fly like super man (Not on all servers)
::xteleall - Teleports all players to where you stand
::pickup #### - Spawns an item depending on what code you enter in
::npc #### - Spawns an NPC depending on the number entered
::pnpc #### - Changes your appearance so that you're an NPC of some sort, depending on the number entered in\
I don't know how you would want them separated so i just put everything together.
