Countdown Spammer

There are spammers around, but I would like to know if anyone could make one to countdown from any number.
For example, if i entered the number '999' it would count down from 999 to 0

988 I guess? I don't get it?

you could use reguluar spamers and just type the numbers and do it like that, i think BMJ did something countdown`ish i cant really remember it though, i think its on realmtools

Yea, i was gunna do that, but the thing is... I actually want to count down from 999 XD
Sooo... yeaa....
