About Tripcodes...

The FAQ here is a little vague on some points:
FAQ says short word.  Must it be a word or can it be a random string?
Max length?
Case sensitive?
Forbidden characters? (I assume # is one)
Link to more in depth info?

Thanks in advance

"false positive" = a tripcode which the search claims to match against that doesn't really match
Excluding tripcodes containing htmlspecialcharsable stuff cuts down on your possible results a lot, too.

I don't see how rand() would be the heaviest consumer, unless it's a shitty rand(), but find a random generator that generates lots of randoms at once. Failing that, at least try the Mersenne Twister.
