Forums Scripts & Popups Idle Msg -- 30 Minute Interval

so, say, I wanted it to be remotly managed... do I do this?

Under Remote:
on *:TEXT:!idle-on:#: { /timerIdleMsg 0 1800 /wa }
on *:TEXT:!idle-off:#: { /timerIdleMsg 0 1800 off }

Under Aliases:
/idle-on /timerIdleMsg 0 1800 /wa
/idle-off /timerIdleMsg 0 1800 off


And this repeats every 30 minutes? ( /wa is an alias )
