The next example adds a /registerme command which rrgisters the player who types it, providing that the resource this example is executed in has sufficient ACL permissions.

function registerUser( player, commandName, username, password, email )
    if getElementType( player ) == "player" then
        if username and password and email then
            if isGuestAccount( getPlayerAccount( player ) ) then
                if isValidMail( email ) then
                    local newAccount = addAccount( username, password )
                    if newAccount then
                        setAccountData( newAccount, "email", email )
                        logIn( player, newAccount, password )
                        outputChatBox( "Now you're logged in your new account.", player, 0, 255, 0 )
                    else
                        outputChatBox( #password > 30 and "The specified password is too long." or "That account already exists.", player, 255, 0, 0 )
