[thelist] Re: Javascript: randomizing persistent text rotator

[Chris Blessing]

Hey Tim-

Your best bet is to have a variable hold the last randomly-generated number,
then use a while loop to check the next generated number against the last
one.  If they're the same, then generate another random number and check it
again until they don't match, THEN execute the rotate function as you have
it.  See if you can get it down with code, lemme know how it turns out!

Good luck,
