You mean, change from checking !->i to checking both !->i and !->l ? (It
does currently check !->i -- did that not work for you in some instance?)

Lemme see about the above suggestions and then you can try it again later
without having to email it...

Well, in the end, the checker is doing more of a "randomness evaluation"
than anything else. Memorability and practicality aside, the best passwords
are those which are close to being truly random and far away from being
generateable by looping or cracking algorithms. So the trick is to find
a password which is still memorable and typeable while being randomish
enough.
